Subject: [PATCH 14/16] file_list: add file_list_detect_all()
Date: Mon,  3 May 2021 13:48:59 +0200	[thread overview]
Message-ID: <20210503114901.13095-15-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20210503114901.13095-1-a.fatoum@pengutronix.de>

This is a common theme along the code that uses file_lists.
Add a function that abstracts it. This could later be used
to simplify this operation in the fastboot code.
