Subject: [PATCH 0/2] of: overlay: avoid potential null pointer exception
Date: Mon, 5 Sep 2022 12:07:15 +0200 [thread overview]
Message-ID: <20220905100717.150557-1-michael.riesch@wolfvision.net> (raw)
Hi all,
The function of_overlay_fix_path returns NULL in certain error cases but
of_overlay_apply_symbols (which is the only caller) does not check the
return value. For broken overlays this may result in a null pointer
exception. Fix this by checking the return value and inform the user
what exactly went wrong. To this end, improve the error handling in
of_overlay_apply_tree.
The thread [0] gives a bit more context.
Best regards,
Michael
