Merge tag 'media/v4.15-2' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media

Pull media fixes from Mauro Carvalho Chehab:

 "A series of fixes for the media subsytem:

   - The largest amount of fixes in this series is with regards to
     comments that aren't kernel-doc, but start with "/**".

     A new check added for 4.15 makes it to produce a *huge* amount of
     new warnings (I'm compiling here with W=1). Most of the patches in
     this series fix those.

     No code changes - just comment changes at the source files

   - rc: some fixed in order to better handle RC repetition codes

   - v4l-async: use the v4l2_dev from the root notifier when matching
     sub-devices

   - v4l2-fwnode: Check subdev count after checking port

   - ov 13858 and et8ek8: compilation fix with randconfigs

   - usbtv: a trivial new USB ID addition

   - dibusb-common: don't do DMA on stack on firmware load

   - imx274: Fix error handling, add MAINTAINERS entry

   - sir_ir: detect presence of port"
