Subject: [PATCH] USB: USB_OTG does not depend on PM
Date: Tue, 17 Nov 2015 22:01:37 +0100 [thread overview]
Message-ID: <7521777.8ZmnT3AlIC@wuerfel> (raw)
USB_OTG initially depended on USB_SUSPEND, which was later turned into
PM_RUNTIME and finally into PM. I don't know at what point the dependency
became unnecessary but it appears to work fine without CONFIG_PM now.
However, we get lots of warnings in randconfig kernels like:
warning: (USB_OTG_FSM && FSL_USB2_OTG && USB_MV_OTG) selects USB_OTG which has unmet direct dependencies (USB_SUPPORT && USB && PM)
whenever CONFIG_PM is disabled and something else selects USB_OTG.
Let's just drop the dependency to avoid the warnings.
