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...
