+Subject: [PATCH] media: i2c: Use the new get_mbus_config pad op
+
+Upstream https://patchwork.linuxtv.org/patch/64669/
+
+Move the existing users of the g_mbus_config video operation to use the
+newly introduced get_mbus_config pad operations.
+
+All the ported drivers report a static media bus configuration and do no
+support s_mbus_config so the operation implementation has not changed.
+
+Bridge drivers needs to call the new pad operation and will receive an
+-ENOICTLCMD when calling the old g_mbus_config video operation
