Merge tag 'gadget-for-v3.8' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next
USB gadget patches from Felipe:
"usb: gadget: patches for v3.8
renesas_usbhs implements ->pullup() method, switches over
to devm_request_irq(), adds support for DMA Engine and
got a few miscelaneous cleanups.
The NCM gadget got an endianness fix and the Ethernet
gadget a frame size fix.
We're finally removing the g_file_storage gadget and
sticking to g_mass_storage and the new tcm_usb_gadget
gadgets since that was a huge duplicaton of effort anyway.
While removing g_file_storage, we also had to fix a bunch
of defconfigs which were still pointing to the old gadget.
There's a big series getting us closer to being able to
introduce our configfs interface. The series converts
functions into loadable modules which will, eventually,
be registered to the configfs interface.
Other than that there's the usual typo fixes and miscelaneous
cleanups all over the place."
