| Subject: Bluetooth: btusb: fix bInterval for high/super speed isochronous endpoints |
| |
| 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. |
