Subject: [PATCH 3.10 175/180] HID: hid-input: Add parentheses to quell gcc warning

From: James C Boyd <jcboyd.dev@...il.com>

commit 09a5c34e8d6b05663ec4c3d22b1fbd9fec89aaf9 upstream.

GCC reports a -Wlogical-not-parentheses warning here; therefore
add parentheses to shut it up and to express our intent more.
