mfd: omap-usb-tll: Fix inverted bit use for USB TLL mode
Commit16fa3dc75c
("mfd: omap-usb-tll: HOST TLL platform driver") added support for USB TLL, but uses OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF bit the wrong way. The comments in the code are correct, but the inverted use of OMAP_TLL_CHANNEL_CONF_ULPINOBITSTUFF causes the register to be enabled instead of disabled unlike what the comments say. Without this change the Wrigley 3G LTE modem on droid 4 EHCI bus can be only pinged few times before it stops responding. Fixes:16fa3dc75c
