Subject: staging: rtl8723au: else is not generally useful after a return
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=444c704321a6e97efbc16d252cbecb5897749221;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: rtl8723au: else is not generally useful after a return

Correct a checkpatch.pl warning regarding rtl8723au's
rtw_security.c::crc32_init pointing out that having an else statement
after a break or a return is not useful.
