blkdev_get variants (and the blk-cgroup special case).  This means that
we now don't need an extra reference in the inode and can generally
simplify handling of struct block_device to keep the lookups contained
in the core block layer code."

so after lookup_bdev call, there no need to do bdput.

remove a superfluous check the bdev & don't call bdput after lookup_bdev.

'maxItems' equal to the 'items' list length is redundant. 'maxItems' is
preferred for a single entry while greater than 1 should have an 'items'
list.

A meta-schema check for this is pending once these existing cases are
fixed.

'memory-region' is a common property, so it doesn't need a type ref here.

*-supply properties are always a single phandle, so binding schemas
don't need a type $ref nor 'maxItems'.

A meta-schema check for this is pending once these existing cases are
fixed.

Pull more ACPI updates from Rafael Wysocki:
 "These make the ACPI enumeration of devices take _DEP information into
  account more aggressively, fix device IDs matching in the ACPI part of
  the PNP devices framework and update the ACPI code related to
  suspend-to-idle to take systems based on AMD hardware into account
  properly.

  Specifics:

   - Modify the ACPI device enumeration code to defer the enumeration of
     devices with an _HID whose lists of operation region dependencies
     returned by _DEP are not empty after eliminating the entries
     representing known-benign dependencies from them (Rafael Wysocki,
     Hans de Goede).

   - Make the ACPI PNP code mathing device IDs also take the length of
     the given ID string into account (Hui Wang).

   - Add AMD systems support to the ACPI code handling suspend-to-idle
     via the PNP0D80 (System Power Management Controller) device _DSM
     interface (Shyam Sundar).

   - Move the suspend-to-idle handling code related to the PNP0D80
     device _DSM interface, which is x86-specific, to a separate file in
     the x86/ subdirectory (Rafael Wysocki)"
