[PATCH 4/5] staging: r8188eu: remove HW_VAR_FWLPS_RF_ON from GetHwReg8188EU()

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Move the functionality of the HW_VAR_FWLPS_RF_ON case in
GetHwReg8188EU() to a static function in rtw_pwrctrl.c and remove the
HW_VAR_FWLPS_RF_ON case from GetHwReg8188EU(). This is part of the
ongoing effort to get rid of the unwanted hal layer.
