2022-05-19tools/thermal: Add thermal daemon skeletonDaniel Lezcano
This change provides a simple daemon skeleton. It is an example of how to use the thermal library which wraps all the complex code related to the netlink and transforms it into a callback oriented code. The goal of this skeleton is to give a base brick for anyone interested in writing its own thermal engine or as an example to rely on to write its own thermal monitoring implementation. In the future, it will evolve with more features and hopefully more logic.

2022-05-19tools/thermal: Add a temperature capture toolDaniel Lezcano

It will write the captured temperature per thermal zone per file so making easier to write a gnuplot script.

2022-05-11thermal: int340x: Mode setting with new OS handshakeSrinivas Pandruvada
With the new OS handshake introduced by commit: "c7ff29763989 ("thermal: int340x: Update OS policy capability handshake")", the "enabled" thermal zone mode doesn't work in the same way as previously. The "enabled" mode fails with -EINVAL when the new handshake is used. To address this issue, when the new OS UUID mask is set: - When the mode is "enabled", return 0 as the firmware already has the latest policy mask. - When the mode is "disabled", update the firmware with the UUID mask of zero. This way, the firmware can take over the thermal control. Also reset the OS UUID mask, which allows user space to update with new set of policies.

2022-05-08floppy: use a statically allocated error counterWilly Tarreau
Interrupt handler bad_flp_intr() may cause a UAF on the recently freed request just to increment the error count. There's no point keeping that one in the request anyway, and since the interrupt handler uses a static pointer to the error which cannot be kept in sync with the pending request, better make it use a static error counter that's reset for each new request. This reset now happens when entering redo_fd_request() for a new request via set_next_request(). One initial concern about a single error counter was that errors on one floppy drive could be reported on another one, but this problem is not real given that the driver uses a single drive at a time, as that PC-compatible controllers also have this limitation by using shared signals. As such the error count is always for the "current" drive.

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus ASoC: Fixes for v5.18 A larger collection of fixes than I'd like, mainly because mixer-test is making it's way into the CI systems and turning up issues on a wider range of systems. The most substantial thing though is a revert and an alternative fix for a dmaengine issue where the fix caused disruption for some other configurations, the core fix is backed out an a driver specific thing done instead.
