From 2a393f5fd872fad99d639812087383111074cfeb Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 15 Jun 2007 15:44:13 -0700 Subject: [PATCH] USB: serial: io_edgeport: clean up urb->status usage This done in anticipation of removal of urb->status, which will make that patch easier to review and apply in the future.
