From a780efa8124fe7ef23d8ef844d56afe960356615 Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Sun, 30 Nov 2008 12:17:12 +0100 Subject: Bluetooth: Handle bulk URBs in btusb driver from notify callback With the addition of usb_unlink_anchored_urbs() it is possible to fully control the bulk URBs from the notify callback. There is no need to schedule work and so only do this for the ISOC URBs.
