Subject: [PATCH 3.2 032/107] [media] rc-core: fix remove uevent generation

3.2.72-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: David Härdeman <david@...deman.nu>

commit a66b0c41ad277ae62a3ae6ac430a71882f899557 upstream.

The input_dev is already gone when the rc device is being unregistered
so checking for its presence only means that no remove uevent will be
generated.
