Subject: [PATCH 09/12] fs: squashfs: remove dead stores for xattr_id
Date: Wed, 30 Sep 2020 09:20:02 +0200	[thread overview]
Message-ID: <20200930072005.1407-9-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200930072005.1407-1-a.fatoum@pengutronix.de>

barebox doesn't do extended attributes in SquashFS. Remove the left-over
xattr_id that's never read.
