[PATCH 6/6] [media] cx24116: Delete jump targets in cx24116_attach()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 30 Aug 2017 08:44:29 +0200

* Return directly after a call of the function "kzalloc" failed
  at the beginning.

* Move a bit of exception handling code into an if branch.

* Delete two jump targets which became unnecessary with this refactoring.
