[PATCH 2/6] [media] cx24116: Return directly after a failed kmalloc() in cx24116_writeregN()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Wed, 30 Aug 2017 07:55:49 +0200

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

* Delete the jump target "error" which became unnecessary
  with this refactoring.
