In case the SAP connection is established before the interface is
added, the mac address is still not set. Don't send the nic info
SAP message in this case since it will result in sending an invalid

In case CSME holds the NIC and SAP connection is already established,
iwl_pcie_prepare_card_hw() during iwl_pci_probe() will fail
(which is fine since CSME will release the nic later when asked with
a SAP message). In this case tring to grab nic access to read the

Avoid the warning by only trying to read the crf ids in case prepare

used to determine when to increase or reduce transmit power: Dynamic
Power Reduction (DPR) on/off. Compared to Static SAR, which has a
constant transmit power, TAS can improve the user experience or

TAS can be enabled through BIOS, and the driver will evaluate

There is the following note at `lib/vsprintf.c:simple_strtoull()` which

And here, simple_str* are explicitly deprecated [3].

This patch also removes an instance of the deprecated `strncpy` which helps [2].

In 'mwifiex_process_sta_txpd()' and 'mwifiex_process_uap_txpd()',
replace 'BUG_ON()' with runtime check, and move all these checks
to 'mwifiex_process_tx()'. This way, both callees may be converted
to 'void', and the caller may be simplified as well.

Return -1 on possible 'mwifiex_write_reg()' errors in
'mwifiex_init_sdio_ioport()', do not ignore the value
returned by the latter in 'mwifiex_init_sdio()' and
'mwifiex_sdio_up_dev()' as well.
