Add a generic helper to match a device by the acpi device.

"by its ACPI companion device object", please.

Sure.


Also, it would be good to combine this patch with the patch(es) that
cause device_match_acpi_dev() to be actually used.

Helpers without any users are arguably not useful.

Sure, the helpers will be part of the part2 of the whole series,
which will actually have the individual subsystems consuming the
new helpers. For your reference, it is available here :

http://linux-arm.org/git?p=linux-skp.git;a=shortlog;h=refs/heads/driver-cleanup/v2

e.g:
http://linux-arm.org/git?p=linux-skp.git;a=commit;h=59534e843e2f214f1f29659993f6e423bef16b28

I could simply pull those patches into this part, if you prefer that.

Not really.

I'd rather do it the other way around: push the introduction of the
helpers to part 2.

Sure, I will do that.


However, that would be true for the other patches in the part2.
I am open to suggestions, on how to split the series.

You can introduce each helper along with its users in one patch.

This way the total number of patches will be reduced and they will be
easier to review IMO.


Wouldn't it make the merging complicated ? I am still not clear how we plan
to merge the part 2 ?
