Subject: [PATCH 0/4] thermal: fix locking regressions in linux-next
Date: Wed, 14 Dec 2022 14:16:13 +0100	[thread overview]
Message-ID: <20221214131617.2447-1-johan+linaro@kernel.org> (raw)

This series fixes some of the fallout after the thermal changes that
just landed in linux-next.

Lockdep reported a lock inversion in one of the Qualcomm drivers and a
closer review revealed that the changes had also broken the sysfs
interface for at least three drivers.

Note that a simple revert of the offending patches was not an option as
some of the infrastructure that the old implementation relied on has
also been removed.
