Merge tag 'thermal-6.4-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull thermal control fixes from Rafael Wysocki:
"These fix a NULL pointer dereference in the Intel powerclamp driver
introduced during the 6.3 cycle and update MAINTAINERS to match recent
code changes.

Specifics:

- Fix NULL pointer access in the Intel powerclamp thermal driver that
occurs on attempts to set the cooling device state to 0 in the
default configuration (Srinivas Pandruvada)

- Drop the stale MAINTAINERS entry for the Intel Menlow thermal
driver that has been removed recently (Lukas Bulwahn)"

* tag 'thermal-6.4-rc1-3' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
