I have been notified that the patch has been applied to 5.15-stable tree, 6.1-stable tree and 6.4-stable tree. http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=summary
I hope it will be incorporated into the Debian kernel. Thanks in advance. -- Takashi Yano <takashi.y...@nifty.ne.jp>
