Yes, also other users have reported "USB breakage" with 4.0-rc1 on N900
etc caused by this.

Commit fbba7db3990cb707ff91cd6507d53a0a730afe97 (usb: musb:
add omap-control dependency) changed USB_MUSB_OMAP2PLUS to depend
on OMAP_CONTROL_PHY but that seems to be wrong at least for OMAP3.
omap_control_phy.h provides dummy functions when it's not enabled.
So there should be no dependency.
