While unloading the driver, the ps_usecount is incremented before configuring gpio registers in deinit_device. But it is failed to restore the ps_usecount after that. The problem is that the chip is forcibly moved to FULL SLEEP by radio_disable when mac80211 is reporting as idle though ps_usecount is not zero. This patch retores ps_usecount properly and ensures that the chip is always moved to full sleep only if ps usage count is zero which also helps in debugging deadbeef on multivif case. And also fixes the following warning. ath: DMA failed to stop in 10 ms AR_CR=0xdeadbeef AR_DIAG_SW=0xdeadbeef ath: Could not stop RX, we could be confusing the DMA engine when we start RX up ------------[ cut here ]------------ WARNING: at drivers/net/wireless/ath/ath9k/recv.c:536 ath_stoprecv+0xf4/0x100 [ath9k]() Cc: stable@kernel.org Cc: Paul Stewart <pstew@google.com> Signed-off-by: Rajkumar Manoharan <rmanoharan@atheros.com> Signed-off-by: John W.
