Subject: [PATCH 4.4 051/137] media: si470x-i2c: add missed operations in remove
From: Chuhong Yuan <hslester96@...il.com>
[ Upstream commit 2df200ab234a86836a8879a05a8007d6b884eb14 ]
The driver misses calling v4l2_ctrl_handler_free and
v4l2_device_unregister in remove like what is done in probe failure.
Add the calls to fix it.
