From d48037f9169f653d1124eb75157293d875e7e57f Mon Sep 17 00:00:00 2001 From: Sudip Mukherjee Date: Fri, 7 Nov 2014 16:50:46 +0530 Subject: [PATCH] staging: rtl8188eu: unneeded NULL check before these NULL checks we are already checking it for NULL, and if it is NULL then we are jumping to the error label and handling the error before returning. So we can reach this part of the code only if the variable is known to be not NULL, and if we already know that it is not NULL, then no need to check it again.
