+From 8b95d0d18fcfb940fb0d171663ce5c93b8fb0024 Mon Sep 17 00:00:00 2001
+From: Dave Stevenson <dave.stevenson@raspberrypi.com>
+Date: Tue, 21 Jan 2020 16:24:45 +0000
+Subject: [PATCH] driver: char: rpivid: Clean up error handling use of
+ ERR_PTR/IS_ERR
+
+The driver used an unnecessary intermediate void* variable so it
+only called ERR_PTR once to convert to the error value.
+
+Switch to converting as the error arises to remove these intermediate
+variables.
