There are few users outside of ACPI realm that re-introduce a custom
solution to match ACPI device against HID/UID. Add a generic helper for
them.
The series is supposed to go via linux-pm tree.
In v2:
- add patch 2 due to latent issue in the header (lkp)
- get rid of match_hid_uid() completely in patch 6
Andy Shevchenko (6):
ACPI / utils: Describe function parameters in kernel-doc
ACPI / utils: Move acpi_dev_get_first_match_dev() under CONFIG_ACPI
ACPI / utils: Introduce acpi_dev_hid_uid_match() helper
ACPI / LPSS: Switch to use acpi_dev_hid_uid_match()
mmc: sdhci-acpi: Switch to use acpi_dev_hid_uid_match()
iommu/amd: Switch to use acpi_dev_hid_uid_match()

We have a stub defined for the acpi_dev_get_first_match_dev() in acpi.h
for the case when CONFIG_ACPI=n.
Moreover, acpi_dev_put(), counterpart function, is already placed under
CONFIG_ACPI.
Thus, move acpi_dev_get_first_match_dev() under CONFIG_ACPI as well.

There are users outside of ACPI realm which reimplementing the comparator
function to check if the given device matches to given HID and UID.
For better utilization, introduce a helper for everyone to use.

For better utilization, introduce a helper for everyone to use.
