From aaed3290f9ffe1428ba8a7f4284f80a165cf453f Mon Sep 17 00:00:00 2001 From: Leo Kim Date: Mon, 12 Oct 2015 16:55:38 +0900 Subject: [PATCH] staging: wilc1000: wilc_wfi_cfgoperations.c : removes unused local variables This patch removes useless local variable, s32Error and returns directly zero from wilc_wfi_cfgoperations.c and also removes incorrect break in switch-case statement. The break is not useless which is being called right after return statement.
