From 74209dc06a7c27401de637cc371f54920d628ba8 Mon Sep 17 00:00:00 2001 From: Frank Schaefer Date: Thu, 8 Nov 2012 14:11:37 -0300 Subject: [PATCH] [media] em28xx: rename struct em28xx_usb_isoc_ctl to em28xx_usb_ctl MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Also rename the corresponding field isoc_ctl in struct em28xx to usb_ctl. We will use this struct for USB bulk transfers, too.
