+Subject: [PATCH] media: i2c: ov9281: Remove override of subdev name
+
+From the original Rockchip driver, the subdev was renamed
+from the default to being "mov9281 <dev_name>" whereas the
+default would have been "ov9281 <dev_name>".
+
+Remove the override to drop back to the default rather than
+a vendor custom string.
