Subject: [PATCH AUTOSEL for 3.18 45/53] media: bt8xx: Fix err 'bt878_probe()'

From: Christophe JAILLET <christophe.jaillet@...adoo.fr>

[ Upstream commit 45392ff6881dbe56d41ef0b17c2e576065f8ffa1 ]

This is odd to call 'pci_disable_device()' in an error path before a
coresponding successful 'pci_enable_device()'.

Return directly instead.

Fixes: 77e0be12100a ("V4L/DVB (4176): Bug-fix: Fix memory overflow")
