From 8143a8963c374116f84aba15dcaeaf02370c8098 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Bj=C3=B8rn=20Mork?= Date: Mon, 16 Jan 2012 15:12:01 +0100 Subject: USB: cdc-wdm: kill the now unnecessary bMaxPacketSize0 field and udev variable MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit We don't need bMaxPacketSize0, and keeping all these different size fields around will only cause us to use the wrong one. Seems the udev variable was only used for getting bMaxPacketSize0. We could have used it for the usb_fill_*_urb() calls, but as it wasn't before - why start now? Instead make the interface_to_usbdev() calls consistent.
