Subject: [PATCH] [media] hdpvr: Refactoring for hdpvr_read()

From: Markus Elfring <elfring@...rs.sourceforge.net>
Date: Tue, 29 Dec 2015 11:02:43 +0100

Let us return directly if the element "status" of the variable "buf"
indicates "BUFSTAT_READY".
A check repetition can be excluded for the variable "ret" at the end then.
