This is a note to let you know that I've just added the patch titled fbdev: mmp: Fix deferred clk handling in mmphw_probe() to the 6.3-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: fbdev-mmp-fix-deferred-clk-handling-in-mmphw_probe.patch and it can be found in the queue-6.3 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable@xxxxxxxxxxxxxxx> know about it. commit 3b42bd86c1b135e63c02bb29749b4c7ac2abe223 Author: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Thu Apr 13 21:33:17 2023 +0200 fbdev: mmp: Fix deferred clk handling in mmphw_probe() [ Upstream commit b3a7a9ab65ae2f2626c7222fb79cdd433f8c5252 ] When dev_err_probe() is called, 'ret' holds the value of the previous successful devm_request_irq() call. 'ret' should be assigned with a meaningful value before being used in dev_err_probe(). While at it, use and return "PTR_ERR(ctrl->clk)" instead of a hard-coded "-ENOENT" so that -EPROBE_DEFER is handled and propagated correctly.
