From df5c37ea9a3820a9515d8204450aec00f48f8f88 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 15 Oct 2006 17:30:45 +0200 Subject: [PATCH] [Bluetooth] Handle return values from driver core functions Some return values of the driver core register and create functions are not handled and so might cause unexpected problems.
