[PATCH] Double-free in cx23885_initdev

[Florin Malita <fmalita@gmail.com>]

Both cx23885_initdev and cx23885_dev_setup free the device in their 
error path so a failure in the latter causes a double-free. Since 
cx23885_dev_setup is only called from cx23885_initdev, it should be safe 
to remove its deallocation and leave the cleanup up to the allocating 
function.

Coverity CID 1922.
