Merge tag 'fixes-for-v3.9-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v3.9-rc4 udc-core learned that it shouldn't use invalid pointers when unloading a gadget driver. net2272 and net2280 got a fix for a regression caused by the udc_start/udc_stop conversion. We're defining a static inline no-op for otg_ulpi_create() to prevent build errors when that driver isn't enabled. FunctionFS got a fix for an off-by-one error when binding and unbinding instances of FunctionFS. MUSB learned that it shouldn't try to unmap buffers which weren't previously mapped. f_rndis got a fix for a possible NULL pointer dereference in a debugging message code. MUSB's DA8xx glue layer got a build fix due to a typo.
