From 8d062b9a3516c6fbcf749bcc864fdb8b3def1caa Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Mon, 23 Apr 2007 17:30:32 -0400 Subject: USB: set the correct Interrupt interval in usb_bulk_msg This patch (as902) fixes a mistake I introduced into usb_bulk_msg(). usb_fill_int_urb() already does the bit-shifting calculation for high-speed Interrupt intervals; it shouldn't be done twice.
