There is a design limitation in host driver. Driver
sends regulatory_hint_user for both user-space and
11d country to kernel. So when wiphy re-registration
happens, kernel tells the source as USER even for 11d.
And per driver logic the 11d needs to be disabled
if INI gCountryCodePriority is set.
To mitigate this issue, storing the country source
in the platform driver.

UHS-I SD cards support SDR104 mode which runs the SD card interface
clock upto 208 MHz. But we may see repeated CRC errors in SDR104
with some SDCC controllers. If this happens, commit <aafc430b36f3>
("mmc: sd: reduce the bus speed in case of multiple CRC errors") would
reinit the card to lower speed (SDR50) hoping that CRC error
rate would reduce at lower clock speed (100MHz for SDR50). As the error
may happen for any cmd, this change tries to fix several other paths -
clock scaling, mmc_rescan, non-data commands error path.

ICL recovery mechanism is used by user space daemon
to recover from adapter collapse during voltage increment
event by reducing the USB ICL. There could be a situation
where nobody votes on usb_icl_votable and this could lead
to a negative ICL value.
Fix this by reading "HW_CURRENT_MAX" property to get ICL in
situations where usb_icl_votable is not voted by any client,
this ensures ICL reduction will always vote a valid ICL.
