ioremap_uc() is only meaningful on old x86-32 systems with the PAT
extension, and on ia64 with its slightly unconventional ioremap()
behavior, everywhere else this is the same as ioremap() anyway.

Change the only driver that still references ioremap_uc() to only do so
on x86-32/ia64 in order to allow removing that interface at some
point in the future for the other architectures.

On some architectures, ioremap_uc() just returns NULL, changing
the driver to call ioremap() means that they now have a chance
of working correctly.

[ Upstream commit 5030b2fe ]

Touch controllers need some time after receiving reset command for the
firmware to finish re-initializing and be ready to respond to commands
from the host. The driver already had handling for the post-reset delay
for I2C and SPI transports, this change adds the handling to
SMBus-connected devices.

SMBus devices are peculiar because they implement legacy PS/2
compatibility mode, so reset is actually issued by psmouse driver on the
associated serio port, after which the control is passed to the RMI4
driver with SMBus companion device.

Note that originally the delay was added to psmouse driver in
92e24e0e

 ("Input: psmouse - add delay when deactivating for SMBus
mode"), but that resulted in an unwanted delay in "fast" reconnect
handler for the serio port, so it was decided to revert the patch and
have the delay being handled in the RMI4 driver, similar to the other
transports.

The RISC-V INTC local interrupts are per-HART (or per-CPU) so we
create INTC IRQ domain only for the INTC node belonging to the boot
HART. This means only the boot HART INTC node will be marked as
initialized and other INTC nodes won't be marked which results
downstream interrupt controllers (such as PLIC, IMSIC and APLIC
direct-mode) not being probed due to missing device suppliers.

To address this issue, we mark all INTC node for which we don't
create IRQ domain as initialized.

commit d61491a5

 ("net/sched: cls_u32: Replace one-element array
with flexible-array member") incorrecly replaced an instance of
`sizeof(*tp_c)` with `struct_size(tp_c, hlist->ht, 1)`. This results
in a an over-allocation of 8 bytes.

This change is wrong because `hlist` in `struct tc_u_common` is a
pointer:

net/sched/cls_u32.c:
struct tc_u_common {
        struct tc_u_hnode __rcu *hlist;
        void                    *ptr;
        int                     refcnt;
        struct idr              handle_idr;
        struct hlist_node       hnode;
        long                    knodes;
};

So, the use of `struct_size()` makes no sense: we don't need to allocate
any extra space for a flexible-array member. `sizeof(*tp_c)` is just fine.

So, `struct_size(tp_c, hlist->ht, 1)` translates to:

sizeof(*tp_c) + sizeof(tp_c->hlist->ht) ==
sizeof(struct tc_u_common) + sizeof(struct tc_u_knode *) ==
						144 + 8  == 0x98 (byes)
						     ^^^
						      |
						unnecessary extra
						allocation size

$ pahole -C tc_u_common net/sched/cls_u32.o
struct tc_u_common {
	struct tc_u_hnode *        hlist;                /*     0     8 */
	void *                     ptr;                  /*     8     8 */
	int                        refcnt;               /*    16     4 */

	/* XXX 4 bytes hole, try to pack */

	struct idr                 handle_idr;           /*    24    96 */
	/* --- cacheline 1 boundary (64 bytes) was 56 bytes ago --- */
	struct hlist_node          hnode;                /*   120    16 */
	/* --- cacheline 2 boundary (128 bytes) was 8 bytes ago --- */
	long int                   knodes;               /*   136     8 */

	/* size: 144, cachelines: 3, members: 6 */
	/* sum members: 140, holes: 1, sum holes: 4 */
	/* last cacheline: 16 bytes */
};

And with `sizeof(*tp_c)`, we have:

	sizeof(*tp_c) == sizeof(struct tc_u_common) == 144 == 0x90 (bytes)

which is the correct and original allocation size.

Fix this issue by replacing `struct_size(tp_c, hlist->ht, 1)` with
`sizeof(*tp_c)`, and avoid allocating 8 too many bytes.

The following difference in binary output is expected and reflects the
desired change:

With the flat mode, we only attempt to allocate large memory if there is an IOMMU
connected to the ETR. If the allocation fails, we always have a fallback path
and return an error if nothing else worked. So, suppress the warning for flat
mode allocations.

[ Upstream commit 41bae58d

 ]

asoc_simple_probe() is used for both "DT probe" (A) and "platform probe"
(B). It uses "goto err" when error case, but it is not needed for
"platform probe" case (B). Thus it is using "return" directly there.

	static int asoc_simple_probe(...)
	{
 ^		if (...) {
 |			...
(A)			if (ret < 0)
 |				goto err;
 v		} else {
 ^			...
 |			if (ret < 0)
(B)				return -Exxx;
 v		}

		...
 ^		if (ret < 0)
(C)			goto err;
 v		...

	err:
(D)		simple_util_clean_reference(card);

		return ret;
	}

Both case are using (C) part, and it calls (D) when err case.
But (D) will do nothing for (B) case.
Because of these behavior, current code itself is not wrong,
but is confusable, and more, static analyzing tool will warning on
(B) part (should use goto err).

To avoid static analyzing tool warning, this patch uses "goto err"
on (B) part.

The driver was interchaning these units when talking about link rate.
Fix this to avoid confusion. Apart from the logging message change,
there is no function change in this commit.

In full-resolution mode, the LPF_INTENSITY_EN and LPF_INTENSITY
registers control Quad Bayer Re-mosaic broken line correction.
Expose this as a module parameter "qbc_adjust": zero disables
the correction and values in the range 2 to 5 set its strength.

There is a trade-off between coloured and monochrome patterns.
The previous fixed value 4 could produce ladder/spots artefacts
in coloured textures. The new default value 2 may suit a wider
range of scenes.
