Subject: [PATCH] hso for error -22 (-EINVAL) printk's
Date: Tue, 16 Sep 2008 16:50:41 +0200	[thread overview]
Message-ID: <48CFC7C1.6020301@option.com> (raw)

Added check for IFF_UP in hso_resume, this should eliminate -EINVAL (-22)
errors caused from urb's being submitted twice, once by hso_resume
& once in hso_net_open, if suspend/resume USB power saving  mode is enabled
