If you, or anyone else, feels it should not be added to the stable tree, please let <stable@vger.kernel.org> know about it. >From fa0fb93f2ac308a76fa64eb57c18511dadf97089 Mon Sep 17 00:00:00 2001 From: Bing Zhao <bz...@marvell.com> Date: Tue, 20 Dec 2011 18:19:00 -0800 Subject: Bluetooth: btusb: fix bInterval for high/super speed isochronous endpoints From: Bing Zhao <bz...@marvell.com> commit fa0fb93f2ac308a76fa64eb57c18511dadf97089 upstream. For high-speed/super-speed isochronous endpoints, the bInterval value is used as exponent, 2^(bInterval-1). Luckily we have usb_fill_int_urb() function that handles it correctly. So we just call this function to fill in the RX URB.
