Subject: [PATCH 0/3] Fix some accidentally dropped IRQ buslocks

In the conversion to scoped guards several buslocks were changed to
plain lock operations. This causes issues with some regmap IRQ
operations as they rely on the bus unlock to synchronise operations back
to the physical chip and those are no longer called.

Thanks,
Charles
