Subject: staging: r8188eu: remove duplicate psta check
X-Git-Tag: v6.6.7~3436^2~171
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=6dd8420d4be40057b4ad015709a05b01f4fb2335;p=platform%2Fkernel%2Flinux-starfive.git

staging: r8188eu: remove duplicate psta check

We do not need the psta check in the while loop of rtw_xmitframe_coalesce.
psta is already checked near the start of the function and is not modified
afterwards.
