+Subject: [PATCH] drm/modes: Don't apply cmdline's rotation if it
+ wasn't specified
+
+Taken from the dri-devel mailing list (11/7/2019) to fixup the cmdline
+parsing, but requires changes as things have moved between 4.19 and 5.2.
+
+From: Dmitry Osipenko <digetx@gmail.com>
+
+The rotation mode from cmdline shouldn't be taken into account if it
+wasn't specified in the cmdline. This fixes ignored default display
+orientation when display mode is given using cmdline without the
+rotation being specified.
+
+Fixes: 1bf4e09227c3 ("drm/modes: Allow to specify rotation and reflection on the commandline")
