From 9597ebac91e5a88f558d236a51d776508d42a237 Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Wed, 22 Sep 2010 18:02:09 +0200 Subject: [PATCH] iwlwifi: remove set_pwr_src operation The set_pwr_src operation is only ever used from within the same sub-driver that it is declared in, so it can just be called directly instead of being an operation. Also, it is never called to set the power source to V_aux, so change the two functions accordingly (but keep the V_aux code for documentation purposes in a comment).
