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"
