[ Upstream commit 29e247ece5d3edfa71495768a9ab5fc7bba76bd4 ]

In case of PCIe interoperability problem shows up, the firmware
payload may be corrupted in download stage. Turn off L0s to keep

destined to us. But after scan, the configuration was wrongly set, so we
fix it.

wifi: mt76: mt7921: reset msta->airtime_ac while clearing up hw value

[ Upstream commit 1bf66dc31032ff5292f4d5b76436653f269fcfbd ]

We should reset mstat->airtime_ac along with clear up the entries in the
hardware WLAN table for the Rx and Rx accumulative airtime. Otherwsie, the
value msta->airtime_ac - [tx, rx]_last may be a negative and that is not
the actual airtime the device took in the last run.

wifi: ath11k: mhi: fix potential memory leak in ath11k_mhi_register()

2022-10-21T10:39:08+00:00

[ Upstream commit 43e7c3505ec70db3d3c6458824d5fa40f62e3e7b ]

mhi_alloc_controller() allocates a memory space for mhi_ctrl. When gets
some error, mhi_ctrl should be freed with mhi_free_controller(). But
when ath11k_mhi_read_addr_from_dt() fails, the function returns without
calling mhi_free_controller(), which will lead to a memory leak.

We can fix it by calling mhi_free_controller() when
ath11k_mhi_read_addr_from_dt() fails.
