From: Vaishali Thakkar Date: Sat, 10 Jan 2015 10:35:32 +0000 (+0530) Subject: Staging: rtl8192u: Remove check of ieee in rtl819x_BAProc.c X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=8dcb6a251aad77d5699486596ea740d5cb0d1570;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git Staging: rtl8192u: Remove check of ieee in rtl819x_BAProc.c This patch fixes following smatch warning: drivers/staging/rtl8192u/ieee80211/rtl819x_BAProc.c:117 ieee80211_ADDBA() warn: variable dereferenced before check 'ieee' (see line 114) As ieee can not be NULL at this point, all such checks are removed.
