[PATCH 0/4] ACPI: Serialize EC queries, UCSI and ideapad methods

[Ali Ahmet Memiş]

This goes on top of [1] and uses its exclusive helpers for the other
users of the shared EC mutex in bko221065: the _Qxx methods, the UCSI
_DSM and the ideapad-laptop methods, as discussed in [2].

Patches 3 and 4 depend on patch 1 and on [1], so it is probably easiest
to take the whole set through the ACPI tree.

The ideapad part is only build-tested, so it would be great if someone
with one of the bko221065 machines could try both series together.
