[PATCH 3/5] fsl_hypervisor: Return the success indication only as a constant in fsl_hv_open()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 20 May 2017 20:05:19 +0200

* Return a success code without storing it in an intermediate variable.

* Delete the local variable "ret" which became unnecessary with
  this refactoring.
