From fa3465689f93331834a831bbe98e3863701e1068 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Wed, 30 Nov 2005 11:57:51 -0500 Subject: [PATCH] USB: UHCI: change uhci_explen macro This patch (as616) changed the uhci_explen macro in uhci-hcd.h so that it now accepts the desired length, rather than length - 1 with special handling for 0. This also fixes a minor bug that would show up only when a driver submits a 0-length bulk URB.
