This is a note to let you know that I've just added the patch titled ASoC: cs42l56: fix DT probe to the 4.19-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-cs42l56-fix-dt-probe.patch and it can be found in the queue-4.19 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit b5f89fef1bddf6844655b872d6d5e2073fcb7d49 Author: Arnd Bergmann <arnd@xxxxxxxx> Date: Thu Jan 26 17:21:24 2023 +0100 ASoC: cs42l56: fix DT probe [ Upstream commit e18c6da62edc780e4f4f3c9ce07bdacd69505182 ] While looking through legacy platform data users, I noticed that the DT probing never uses data from the DT properties, as the platform_data structure gets overwritten directly after it is initialized. There have never been any boards defining the platform_data in the mainline kernel either, so this driver so far only worked with patched kernels or with the default values. For the benefit of possible downstream users, fix the DT probe by no longer overwriting the data.
