Message-Id: <5f61fec0dbc7d50715800c94b19db5914b1af610.1414387334.git.joe@perches.com> Date: Sun, 26 Oct 2014 22:25:05 -0700 From: Joe Perches <joe@...ches.com> To: linux-kernel@...r.kernel.org, Jiri Kosina <jkosina@...e.cz>, David Sterba <dsterba@...e.cz> Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, Jiri Slaby <jslaby@...e.cz> Subject: [PATCH 09/11] tty: ipwireless: 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. Add parentheses around the masks.
