Subject: [GIT PULL] Thermal control updates for v6.2-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 thermal-6.2-rc1

with top-most commit 75b15aa0d83ec835082129b62e8cb9a44703ad72

 Merge branch 'thermal-intel'

on top of commit 247f34f7b80357943234f93f247a1ae6b6c3a740

 Linux 6.1-rc2

to receive thermal control updates for 6.2-rc1.

These include thermal core fixes to protect thermal device operations
against thermal device removal, other thermal core fixes and updates of
Intel thermal control drivers.

Specifics:

 - Fix race conditions related to thermal device operations that are not
   protected against thermal device removal (Guenter Roeck).

 - Fix error code in __thermal_cooling_device_register() (Dan Carpenter).

 - Validate new cooling device state (coming from user space) in
   cur_state_store() and reuse the max_state value from cooling device
   structure in the sysfs interface (Viresh Kumar).

 - Fix some possible name leaks in error paths in the thermal control
   core code (Yang Yingliang).

 - Detect TCC lock bit set in the intel_tcc_cooling driver and make it
   refuse to update the TCC offset in that case (Zhang Rui).

 - Add TCC cooling support for RaptorLake-S (Zhang Rui).

 - Prevent accidental clearing of HFI status by one of the other
   drivers using the same status register (Srinivas Pandruvada).

 - Protect clearing of thermal status bits in Intel thermal control
   drivers (Srinivas Pandruvada).

 - Allow the HFI thermal control driver to ACK an HFI event for the
   previously observed timestamp (Srinivas Pandruvada).

 - Remove a pointless die_id check from the HFI thermal driver and
   adjust the definition of a data structure used by it (Ricardo Neri).

The above said, there is potentially more thermal control material for
6.2, but I only received a pull request for it from Daniel on Friday
(https://patchwork.kernel.org/project/linux-pm/patch/3ccca41f-0899-b205-903b-ec8c742f3e91@linaro.org/).

It is not included here, because in my view it hasn't received
sufficient linux-next coverage yet, at least in its current form (some
of it was in linux-next before, but then it had to be rebased on top
of the fixes mentioned above), but deferring it by a whole release
cycle wouldn't be my choice either.  In this particular case, the
reason for the delay was an unfortunate coincidence of events rather
than anything else (Daniel's extended sick leave that prevented him
from being able to participate in the development process while he had
had quite a bit of work staged already that overlapped with the
submission of important fixes).  While I realize that this is a "late"
merge window, deferring stuff from people that was submitted timely,
but had not been processed because of a maintainer's absence that
wasn't his fault, feels a bit harsh.

I would really appreciate it if you please give me your recommendation
regarding the extra thermal control material.  Would you like to
receive a pull request with it later during this merge window, or
would you prefer it to wait for the 6.3 one?

Thanks!
