Subject: staging: r8188eu: remove HW_VAR_ACK_PREAMBLE from SetHwReg8188EU()
X-Git-Tag: v6.6.17~7348^2~283
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=484e4259a6a9ccad7f08f13fefcba3b976256b37;p=platform%2Fkernel%2Flinux-rpi.git

staging: r8188eu: remove HW_VAR_ACK_PREAMBLE from SetHwReg8188EU()

Remove the HW_VAR_ACK_PREAMBLE case from SetHwReg8188EU() and move
its functionality to rtw_wlan_util.c where it is actually used. This
is part of the ongoing effort to get rid of the unwanted hal layer.
