Subject[PATCH 3.13 106/187] mfd: omap-usb-host: Fix improper mask use.
Date
3.13.11.7 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Michael Welling <mwelling@emacinc.com>

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.
