Message-Id: <8c6687a4d568c853ab649ba03d2477ee24bc6ff6.1414387334.git.joe@perches.com> Date: Sun, 26 Oct 2014 22:24:59 -0700 From: Joe Perches <joe@...ches.com> To: linux-kernel@...r.kernel.org Cc: Dmitry Torokhov <dmitry.torokhov@...il.com>, linux-input@...r.kernel.org Subject: [PATCH 03/11] aiptek: Fix probable mask then right shift defects Precedence of & and >> is not the same and is not left to right. shift has higher precedence and should be done after the mask. Here the shifts are unnecessary and a non-zero value can be used as the test to set 1 or zero.
