From 98a63aaf245e2522b0ddd86f38fb83883344bcaf Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 20 Oct 2015 23:25:42 +0200 Subject: [PATCH] Bluetooth: Introduce driver specific post init callback Some drivers might have to restore certain settings after the init procedure has been completed. This driver callback allows them to hook into that stage. This callback is run just before the controller is declared as powered up.
