From 52de599e04e8767b0d9b7874451cb5db91a4a70b Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Tue, 3 Sep 2013 18:08:38 -0700 Subject: [PATCH] Bluetooth: Only schedule raw queue when user channel is active When the user channel is set and an user application has full control over the device, do not bother trying to schedule any queues except the raw queue. This is an optimization since with user channel, only the raw queue is in use.
