From 0f3adeae6011fe82ccdee858dad6b7b2bd790add Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Fri, 26 Dec 2014 04:42:34 +0100 Subject: [PATCH] Bluetooth: Remove BlueFritz! specific check from initialization The AVM BlueFritz! USB controllers had a special handling in the Bluetooth core when it comes to reading the supported commands. Both drivers now set the HCI_QUIRK_BROKEN_LOCAL_COMMANDS and with that it is no longer needed to look for vendor specific details.
