[PATCH 3.14 23/42] Bluetooth: Ignore isochronous endpoints for Intel USB bootloader

From: Greg Kroah-Hartman
Date: Sun Apr 26 2015 - 10:12:09 EST


3.14-stable review patch. If anyone has any objections, please let me know.

------------------

From: Marcel Holtmann <marcel@xxxxxxxxxxxx>

commit d92f2df0565ea04101d6ac04bdc10feeb1d93c94 upstream.

The isochronous endpoints are not valid when the Intel Bluetooth
controller boots up in bootloader mode. So just mark these endpoints
as broken and then they will not be configured.
