X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=eb8329c6b39db6bc52c43265fb0c41367d99a6d2;p=linux-beck.git

Staging: rtl8188eu: removed unnecessary check in core/rtw_ap.c

This patch removes unnecessary "if (true)" check in update_BCNTIM()
from core/rtw_ap.c file. After this remove the code alignment was
necessary.
