+
+
+From: Arnd Bergmann <arnd@arndb.de>
+
+Replaces upstream commit 0b2e9e7947e7 ("media: staging/imx: remove
+confusing IS_ERR_OR_NULL usage")
+
+We get a harmless warning about a potential uninitialized variable
+use in the driver:
+
+drivers/staging/media/imx/imx-media-of.c: In function 'of_parse_subdev':
+drivers/staging/media/imx/imx-media-of.c:216:4: warning: 'remote_np' may be used uninitialized in this function [-Wmaybe-uninitialized]
+
+I reworked that code to be easier to understand by gcc in mainline,
+but that commit is too large to backport. This is a much simpler
+workaround, avoiding the warning by adding a fake initialization
+to the variable. The driver was only introduced in linux-4.13,
+so the workaround is not needed for earlier stable kernels.
+
+Fixes: e130291212df ("[media] media: Add i.MX media core driver")
