Merge tag 'media/v4.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:
 "Media regression fixes:

   - serial_ir: fix a Kernel crash during boot on Kernel 4.11-rc1, due
     to an IRQ code called too early

   - other IR regression fixes at lirc and at the raw IR decoding

   - a deadlock fix at the RC nuvoton driver

   - fix another issue with DMA on stack at dw2102 driver

  There's an extra patch there that change a driver interface for the
  SoC VSP1 driver, with is shared between the DRM and V4L2 driver. The
  patch itself is trivial, and was acked by David Arlie"

* tag 'media/v4.11-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media:
  [media] v4l: vsp1: Adapt vsp1_du_setup_lif() interface to use a structure
  [media] dw2102: don't do DMA on stack
  [media] rc: protocol is not set on register for raw IR devices
  [media] rc: raw decoder for keymap protocol is not loaded on register
  [media] rc: nuvoton: fix deadlock in nvt_write_wakeup_codes
  [media] lirc: fix dead lock between open and wakeup_filter
  [media] serial_ir: ensure we're ready to receive interrupts
