Subject: [PATCH] of: base: make of_device_compatible_match() accept const device node
Date: Thu, 29 Sep 2022 17:32:49 -0700 [thread overview]
Message-ID: <YzY5MaU5N4A2st5R@google.com> (raw)
of_device_is_compatible() accepts const device node pointer, there is
no reason why of_device_compatible_match() can't do the same.
