Subject: [PATCH] media: si470x-i2c: add missed operations in remove
Git-commit: 2df200ab234a86836a8879a05a8007d6b884eb14
Patch-mainline: v5.5-rc1
References: git-fixes

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.
