From 6fcdcf04e391c033eb9a558a744d8729d52e646e Mon Sep 17 00:00:00 2001 From: Greg Kroah-Hartman Date: Fri, 15 Jun 2007 15:44:13 -0700 Subject: USB: serial: kobil_sct: 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.
