Merge tag 'fixes-for-v4.11-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-linus
Felipe writes: usb: fixes for v4.11-rc4 f_acm got an endianness fix by Oliver Neukum. This has been around for a long time but it's finally fixed. f_hid learned that it should never access hidg->req without first grabbing the spinlock. Roger Quadros fixed two bugs in the f_uvc function driver. Janusz Dziedzic fixed a very peculiar bug with EP0, one that's rather difficult to trigger. When we're dealing with bounced EP0 requests, we should delay unmap until after ->complete() is called. UDC class got a use-after-free fix.
