This is a note to let you know that I've just added the patch titled reset: Fix devm bulk optional exclusive control getter to the 5.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary The filename of the patch is: reset-fix-devm-bulk-optional-exclusive-control-gette.patch and it can be found in the queue-5.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit aa7edb2cd059d46013d6153046fc1aa1afc4056e Author: Serge Semin <Sergey.Semin@xxxxxxxxxxxxxxxxxxxx> Date: Fri Jun 24 17:18:45 2022 +0300 reset: Fix devm bulk optional exclusive control getter [ Upstream commit a57f68ddc8865d59a19783080cc52fb4a11dc209 ] Most likely due to copy-paste mistake the device managed version of the denoted reset control getter has been implemented with invalid semantic, which can be immediately spotted by having "WARN_ON(shared && acquired)" warning in the system log as soon as the method is called. Anyway let's fix it by altering the boolean arguments passed to the __devm_reset_control_bulk_get() method from - shared = true, optional = false, acquired = true to + shared = false, optional = true, acquired = true That's what they were supposed to be in the first place (see the non-devm version of the same method: reset_control_bulk_get_optional_exclusive()).
