Subject: [ 10/16] USB: add USB_VENDOR_AND_INTERFACE_INFO() macro
Date: Sun, 19 Aug 2012 20:56:09 -0700 [thread overview]
Message-ID: <20120820035459.124021821@linuxfoundation.org> (raw)
In-Reply-To: <20120820035457.653002510@linuxfoundation.org>
From: Greg KH <gregkh@linuxfoundation.org>
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
commit d81a5d1956731c453b85c141458d4ff5d6cc5366 upstream.
A lot of Broadcom Bluetooth devices provides vendor specific interface
class and we are getting flooded by patches adding new device support.
This change will help us enable support for any other Broadcom with vendor
specific device that arrives in the future.
Only the product id changes for those devices, so this macro would be
perfect for us:
{ USB_VENDOR_AND_INTERFACE_INFO(0x0a5c, 0xff, 0x01, 0x01) }
