From eec08eecb892a47fba01fc1762d299e84ba98224 Mon Sep 17 00:00:00 2001 From: Michael Welling Date: Mon, 28 Jul 2014 18:01:04 -0500 Subject: [PATCH] mfd: omap-usb-host: Fix improper mask use. commit 46de8ff8e80a6546aa3d2fdf58c6776666301a0c upstream. single-ulpi-bypass is a flag used for older OMAP3 silicon. The flag when set, can excite code that improperly uses the OMAP_UHH_HOSTCONFIG_UPLI_BYPASS define to clear the corresponding bit. Instead it clears all of the other bits disabling all of the ports in the process.
