usb: fixes for v3.12-rc2
Here's first set of fixes for v3.12-rc series, patches have
been soaking in linux-usb for a while now.
We have the usual sparse and build warnings, a Kconfig fix
to a mismerge on dwc3 Kconfig, fix for a possible memory leak
in dwc3, s3c-hsotg won't disconnect when bus goes idle, locking
fix in mv_u3d_core, endpoint disable fix in f_mass_storage.
We also have one device ID added to dwc3's PCI glue layer in order
to support Intel's BayTrail devices.
