[PATCH v2] staging: rtl8723bs: remove unnecessary boolean comparisons in rtw_recv.c
Posted by Ashwin Gundarapu 1 day, 8 hours ago
Remove explicit comparisons to true and false. Replace '== false'
with the '!' operator and remove '== true' entirely.

This patch doesn't apply to the staging-next tree. 

I have recently done a massive cleanup of this driver and removed
these boolean comparisons. So please rebase your local tree and check
if there is anything left that is worth your effort.

Andrei
