Merge tag 'thermal-5.16-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull more thermal control updates from Rafael Wysocki:
"These fix two issues in the thermal core and one in the int340x
thermal driver.

Specifics:

- Replace pr_warn() with pr_warn_once() in user_space_bind() to
reduce kernel log noise (Rafael Wysocki).

- Extend the RFIM mailbox interface in the int340x thermal driver to
return 64 bit values to allow all values returned by the hardware
to be handled correctly (Srinivas Pandruvada).

- Fix possible NULL pointer dereferences in the of_thermal_ family of
functions (Subbaraman Narayanamurthy)"
