Analyze and fix the following issue in the Linux kernel code: ath9k_hw: fix BT sleep state on chip wakeup
Problem Details: Whenever both WLAN and BT in/out sleep mode, sometimes WLAN is not able to take back the shared LNA control after resumes from sleep mode. The idea is that for WLAN to check if BT owns LNA control and BT is in sleep mode when WLAN just resumes from sleep mode. If the condition is true, do a BTCOEX_RC_W...

Analyze and fix the following issue in the Linux kernel code: ath9k: Disable ASPM only for AR9285
Problem Details: Currently, ASPM is disabled for all WLAN+BT combo chipsets when BTCOEX is enabled. This is incorrect since the workaround is required only for WB195, which is a AR9285+AR3011 combo solution. Fix this by checking for the HW version when enabling the workaround.
