+From: Matthias Fend <matthias.fend@emfend.at>
+Date: Wed, 31 Aug 2022 16:54:20 +0200
+Subject: [PATCH] do not use git information for version generation
+
+Since libcamera is checked out without a git repo, git version reports the
+version of the BSP. Since this is obviously wrong, just use the project
+version.
