From f12919d5c9540ae01ca42f480ccec0fd8c70a6ad Mon Sep 17 00:00:00 2001 From: Elena Oat Date: Tue, 18 Mar 2014 19:16:49 +0200 Subject: [PATCH] Staging: rtl8188eu: Fix warning of unchecked sscanf return value. This patch fixes the warning "unchecked sscanf return value" in file rtw_mp.c. Zero is returned in case sscanf fails or if less than expected items are read and assigned successfully. I have decided to return zero, because in previous conditional statements zero was returned in case of failure. While at it, I have also fixed the warning of line over 80 characters.
