Subject: [PATCH 2/2] [media] tuners: Refactoring for m88rs6000t_sleep()

From: Markus Elfring <elfring@...rs.sourceforge.net>

This issue was detected by using the Coccinelle software.

1. Let us return directly if a call of the regmap_write() function failed.

2. Delete the jump label "err" then.

3. Return zero as a constant at the end.
