[ Upstream commit 9d7b132e ] The gpiod_lookup_table.table passed to gpiod_add_lookup_table() must be terminated with an empty entry, add this. Note we have likely been getting away with this not being present because the GPIO lookup code first matches on the dev_id, causing most lookups to skip checking the table and the lookups which do check the table will find a matching entry before reaching the end. With that said, terminating these tables properly still is obviously the correct thing to do. Fixes: f8eb0235 ("x86: pcengines apuv2 gpio/leds/keys platform driver") Signed-off-by:

[ Upstream commit 704e624f ] On s390, the following build warning occurs: drivers/net/ethernet/marvell/mvpp2/mvpp2.h:844:2: warning: overflow in conversion from 'long unsigned int' to 'int' changes value from '18446744073709551584' to '-32' [-Woverflow] 844 | ((total_size) - MVPP2_SKB_HEADROOM - MVPP2_SKB_SHINFO_SIZE) This happens because MVPP2_SKB_SHINFO_SIZE, which is 320 bytes (which is already 64-byte aligned) on some architectures, actually gets ALIGN'd up to 512 bytes in the s390 case. So then, when this is invoked: MVPP2_RX_MAX_PKT_SIZE(MVPP2_BM_SHORT_FRAME_SIZE) ...that turns into: 704 - 224 - 512 == -32 ...which is not a good frame size to end up with! The warning above is a bit lucky: it notices a signed/unsigned bad behavior here, which leads to the real problem of a frame that is too short for its contents. Increase MVPP2_BM_SHORT_FRAME_SIZE by 32 (from 704 to 736), which is just exactly big enough. (The other values can't readily be changed without causing a lot of other problems.)

[ Upstream commit 8b353bbe ] The driver was defining two ALSA controls that both change the same register field for the wind noise filter corner frequency. The filter response has two corners, at different frequencies, and the duplicate controls most likely were an attempt to be able to set the value using either of the frequencies. However, having two controls changing the same field can be problematic and it is unnecessary. Both frequencies are related to each other so setting one implies exactly what the other would be. Removing a control affects user-side code, but there is currently no known use of the removed control so it would be best to remove it now before it becomes a problem. Signed-off-by:

commit b93dfa6b upstream. Fix the NFIT parsing code to treat a 0 index in a SPA Range Structure as a special case and not match Region Mapping Structures that use 0 to indicate that they are not mapped. Without this fix some platform BIOS descriptions of "virtual disk" ranges do not result in the pmem driver attaching to the range. Details: In addition to typical persistent memory ranges, the ACPI NFIT may also convey "virtual" ranges. These ranges are indicated by a UUID in the SPA Range Structure of UUID_VOLATILE_VIRTUAL_DISK, UUID_VOLATILE_VIRTUAL_CD, UUID_PERSISTENT_VIRTUAL_DISK, or UUID_PERSISTENT_VIRTUAL_CD. The critical difference between virtual ranges and UUID_PERSISTENT_MEMORY, is that virtual do not support associations with Region Mapping Structures. For this reason the "index" value of virtual SPA Range Structures is allowed to be 0. If a platform BIOS decides to represent NVDIMMs with disconnected "Region Mapping Structures" (range-index == 0), the kernel may falsely associate them with standalone ranges where the "SPA Range Structure Index" is also zero. When this happens the driver may falsely require labels where "virtual disks" are expected to be label-less. I.e. "label-less" is where the namespace-range == region-range and the pmem driver attaches with no user action to create a namespace.

commit bf2ba432 upstream. Function ceph_check_delayed_caps() is called from the mdsc->delayed_work workqueue and it can be kept looping for quite some time if caps keep being added back to the mdsc->cap_delay_list. This may result in the watchdog tainting the kernel with the softlockup flag. This patch breaks this loop if the caps have been recently (i.e. during the loop execution). Any new caps added to the list will be handled in the next run. Also, allow schedule_delayed() callers to explicitly set the delay value instead of defaulting to 5s, so we can ensure that it runs soon afterward if it looks like there is more work.

commit 3a715e80 upstream. FPU_STATUS register contains FP exception flags bits which are updated by core as side-effect of FP instructions but can also be manually wiggled such as by glibc C99 functions fe{raise,clear,test}except() etc. To effect the update, the programming model requires OR'ing FWE bit (31). This bit is write-only and RAZ, meaning it is effectively auto-cleared after write and thus needs to be set everytime: which is how glibc implements this. However there's another usecase of FPU_STATUS update, at the time of Linux task switch when incoming task value needs to be programmed into the register. This was added as part of f45ba2bd ("ARCv2: fpu: preserve userspace fpu state") which missed OR'ing FWE bit, meaning the new value is effectively not being written at all. This patch remedies that. Interestingly, this snafu was not caught in interm glibc testing as the race window whi...

commit acc68b8d upstream. The CPSW switchdev driver inherited fix from commit 9421c901 ("net: ethernet: ti: cpsw: fix min eth packet size") which changes min TX packet size to 64bytes (VLAN_ETH_ZLEN, excluding ETH_FCS). It was done to fix HW packed drop issue when packets are sent from Host to the port with PVID and un-tagging enabled. Unfortunately this breaks some other non-switch specific use-cases, like: - [1] CPSW port as DSA CPU port with DSA-tag applied at the end of the packet - [2] Some industrial protocols, which expects min TX packet size 60Bytes (excluding FCS). Fix it by configuring min TX packet size depending on driver mode - 60Bytes (ETH_ZLEN) for multi mac (dual-mac) mode - 64Bytes (VLAN_ETH_ZLEN) for switch mode and update it during driver mode change and annotate with READ_ONCE()/WRITE_ONCE() as it can be read by napi while writing.

commit 86ff25ed upstream. If an i2c driver happens to not provide the full amount of data that a user asks for, it is possible that some uninitialized data could be sent to userspace. While all in-kernel drivers look to be safe, just be sure by initializing the buffer to zero before it is passed to the i2c driver so that any future drivers will not have this issue. Also properly copy the amount of data recvieved to the userspace buffer, as pointed out by Dan Carpenter. Reported-by:

commit 2e6b8363 upstream. PCM buffers might be allocated dynamically when the buffer preallocation failed or a larger buffer is requested, and it's not guaranteed that substream->dma_buffer points to the actually used buffer. The address should be retrieved from runtime->dma_addr, instead of substream->dma_buffer (and shouldn't use virt_to_phys). Also, remove the line overriding runtime->dma_area superfluously, which was already set up at the PCM buffer allocation.

commit 2c39ca68 upstream. The tlv320aic31xx driver relies on regcache_sync() to restore the register contents after going to _BIAS_OFF, for example during system suspend. This does not work for the jack detection configuration since that is configured via the same register that status is read back from so the register is volatile and not cached. This can also cause issues during init if the jack detection ends up getting set up before the CODEC is initially brought out of _BIAS_OFF, we will reset the CODEC and resync the cache as part of that process. Fix this by explicitly reapplying the jack detection configuration after resyncing the register cache during power on. This issue was found by an engineer working off-list on a product kernel, I just wrote up the upstream fix. Signed-off-by:

commit 827f3164 upstream. Along with the transition to the managed PCM buffers, the driver now accepts the dynamically allocated buffer, while it still kept the reference to the old preallocated buffer address. This patch corrects to the right reference via runtime->dma_addr. (Although this might have been already buggy before the cleanup with the managed buffer, let's put Fixes tag to point that; it's a corner case, after all.)

commit 84edec86 upstream. The datasheets have the following note for the conversion time specification: "This parameter is specified by design and/or characterization and it is not tested in production." Parts have been seen that require more time to do 14-bit conversions for the relative humidity channel. The result is ENXIO due to the address phase of a transfer not getting an ACK. Delay an additional 1 ms per conversion to allow for additional margin. Fixes: 4839367d ("iio: humidity: add HDC100x support") Signed-off-by:

commit 9898cb24 upstream. The ADS7950 requires that CS is deasserted after each SPI word. Before commit e2540da8 ("iio: adc: ti-ads7950: use SPI_CS_WORD to reduce CPU usage") the driver used a message with one spi transfer per channel where each but the last one had .cs_change set to enforce a CS toggle. This was wrongly translated into a message with a single transfer and .cs_change set which results in a CS toggle after each word but the last which corrupts the first adc conversion of all readouts after the first readout.
