From 6a070e6e81adfaed060c5696ef3388126d2165b1 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Thu, 31 Oct 2013 04:54:33 -0700 Subject: [PATCH] Bluetooth: Store supported commands only during setup procedure The list of supported commands of a controller can not change during its lifetime. So store the list just once during the setup procedure and not every time the HCI command is executed.
