Hi,

there is a kernel panic on a rock960 board:

After git bisecting, I have:

commit 14facbc1871ae15404666747b5319c08e04b875a
Merge: f5c97da8037b 32346491ddf2
Author: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date:   Mon Jul 11 08:32:58 2022 +0200

     Merge 5.19-rc6 into char-misc-next

     We need the misc driver fixes in here as well.

     Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Any clue?
