[PATCH] ath: change logging functions to return void

From: Joe Perches
Date: Mon Sep 22 2014 - 13:35:48 EST


The return values are not used by callers of these functions
so change the functions to return void.

Other miscellanea:

o add __printf verification to wil6210 logging functions
No format/argument mismatches found

This change is associated to a desire to eventually
change printk to return void.
