Merge tag 'device-id-rework' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux

Pull mod_devicetable.h header split from Uwe Kleine-König:
 "Split <linux/mod_devicetable.h> in per subsystem headers

  <linux/mod_devicetable.h> is included transitively in nearly every
  driver in an x86_64 allmodconfig build of v7.1:

      $ find drivers -name \*.o -not -name \*.mod.o | wc -l
      21330
      $ find drivers -name \*.o.cmd -not -name \*.mod.o.cmd | xargs grep -l mod_devicetable.h | wc -l
      17038

  The result of this mixture of different and unrelated subsystem
  details is that even when touching an obscure device id struct most of
  the kernel needs to be recompiled. Given that each driver typically
  only needs one or two of these structures, splitting into per
  subsystem headers and only including what is really needed reduces the
  amount of needed recompilation.

  This split is implemented in the first commit and then after some
  preparatory work in the following commits, the last two replace
  includes of <linux/mod_devicetable.h> by the actually needed more
  specific headers.

  There are still a few instances left, but the ones with high impact
  (that is in headers that are used a lot) and the easy ones (.c files)
  are handled. These remaining includes will be addressed during the
  next merge window"
