From 99a82f734aa6c6d397e029e6dfa933f04e0fa8c8 Mon Sep 17 00:00:00 2001 From: Larry Finger Date: Fri, 28 Nov 2014 10:41:14 -0600 Subject: [PATCH] rtlwifi: rtl8192ce: Fix editing error that causes silent memory corruption In the major update of the rtlwifi-family of drivers, there was an editing mistake. Unfortunately, this particular error leads to memory corruption that silently leads to failure of the system. This patch is one of three needed to fix the kernel regression reported at https://bugzilla.kernel.org/show_bug.cgi?id=88951.
