From 14ff96e04c0b29736c8c81fbe75e86dd373c8e22 Mon Sep 17 00:00:00 2001 From: Felipe Balbi Date: Wed, 21 Dec 2011 13:13:33 +0200 Subject: [PATCH] usb: renesas: pipe: convert a long if into a XOR operation This is just a minor optimization for the long if we have on the driver. When we want to check that one input is true and the other must be false, the bitwise XOR operator will achieve that for us.
