This is a note to let you know that I've just added the patch titled

Input: ims-pcu - fix calling interruptible mutex

to the 6.11-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git%3Ba=su...

The filename of the patch is: input-ims-pcu-fix-calling-interruptible-mutex.patch and it can be found in the queue-6.11 subdirectory.

If you, or anyone else, feels it should not be added to the stable tree, please let stable@vger.kernel.org know about it.

Did you manage to pick up 703f12672e1f ("Input: ims-pcu - switch to using cleanup functions") for stable? I would love to see the justification for that...

[ Upstream commit 82abef590eb31d373e632743262ee7c42f49c289 ] Fix calling scoped_cond_guard() with mutex instead of mutex_intr. scoped_cond_guard(mutex, ...) will call mutex_lock() instead of mutex_lock_interruptible().
