From ec97423afbd09c566fc3e756b4a6b50695dda0af Mon Sep 17 00:00:00 2001 From: Levente Kurusa Date: Fri, 14 Feb 2014 22:50:23 +0100 Subject: [PATCH] staging: rtl8821ae: fix invalid bit mask on MSR_AP check Since MSR_AP is 0x3, ANDing it with 0xFC will never be true. Add a NOT operation to 0xFC so that we will AND with the last three bits which will result in a possibility that the condition will succeed.
