Subject: ath9k_hw: remove bogus register write on ath9k_hw_9271_pa_cal()
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=1d9c185d67e61737562befdc6b0c4f19b6a85be6;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

ath9k_hw: remove bogus register write on ath9k_hw_9271_pa_cal()

An extra register was being written to for PA calibration
making the hardware unresponsive, remove it. Hardware
reset should now complete fine on ar9271.
