Subject: [PATCH 1/2] [media] tuners: Delete an error message for a failed
 memory allocation in m88rs6000t_probe()

* Omit an extra message for a memory allocation failure in this function.

  This issue was detected by using the Coccinelle software.

* Add a jump target so that the function "kfree" will be always called
  with a non-null pointer.
