From 1753b40f5c97e0d0bf2f0a562603cfc592945a5e Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Sun, 26 Oct 2014 22:25:02 -0700 Subject: [PATCH] mfd: wm8350-core: Fix probable mask then right shift defect Precedence of & and >> is not the same and is not left to right. shift has higher precedence and should be done after the mask. Add parentheses around the mask.
