MT7663s have to rely on MMC_PM_KEEP_POWER in pm_flags for to avoid SDIO power is being shut off. To fix sdio access failure like "mt7663s mmc1:0001:1: sdio write failed: -22" for the first sdio command to access the bus in the resume handler.

Queueing a per-sta work item from the tx free path can become very expensive under load. This work is only supposed to pull rate control stats every second and deal with rate control changes. Additionally, the rate control update code was wrong, because it was confusing bit masks and bit numbers in test_bit. Fix this by introducing a dedicated device work item for rate control updates, and by polling station stats from the phy mac work. Stations requiring polling or rate control updates are added to lists protected by dev->sta_poll_lock. Signed-off-by: -

If rtw_core_init() fails to load the wow firmware, rtw_core_deinit() will not get called to clean up the regular firmware. Ensure that an error loading the wow firmware does not produce an oops for the regular firmware by waiting on its completion to be signalled before returning. Also release the loaded firmware.
