| |
3.0-stable review patch. If anyone has any objections, please let me know.
------------------
From: Bing Zhao <bzhao@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.
