From 70da624376b8ba8d0db83eb817a7bc140778a26f Mon Sep 17 00:00:00 2001 From: Johan Hedberg Date: Fri, 15 Mar 2013 17:06:51 -0500 Subject: [PATCH] Bluetooth: Move power on HCI command updates to their own function These commands will in a subsequent patch be performed in their own asynchronous request, so it's more readable (not just from a resulting code perspective but also the way the patches look like) to have them performed in their own function.
