<linux/mod_devicetable.h> is included in a many files:
$ git grep '<linux/mod_devicetable.h>' ef0c9f75a1 | wc -l
1598
; some of them are widely used headers. To stop mixing up different and
unrelated driver( type)s let the subsystem headers only use the subset
of the recently split <linux/mod_devicetable.h> that are relevant for
them.
The fallout (I hope) is addressed in the previous commits that handle
sources relying on e.g. <linux/i2c.h> pulling in the full legacy header
and thus providing pci_device_id.
