This is a note to let you know that I've just added the patch titled ASoC: Intel: boards: always check the result of acpi_dev_get_first_match_dev() to the 6.11-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: asoc-intel-boards-always-check-the-result-of-acpi_de.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@xxxxxxxxxxxxxxx> know about it. commit db0332dbcb40222b8b236880d3446e48b353c014 Author: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxx> Date: Tue Aug 27 20:32:01 2024 +0800 ASoC: Intel: boards: always check the result of acpi_dev_get_first_match_dev() [ Upstream commit 14e91ddd5c02d8c3e5a682ebfa0546352b459911 ] The code seems mostly copy-pasted, with some machine drivers forgetting to test if the 'adev' result is NULL. Add this check when missing, and use -ENOENT consistently as an error code.
