Subject: hso: Fix URB submission -EINVAL.
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=89930b7b5e3e9bfe9c6ec5e19920451c8f5d9088;p=openwrt%2Fstaging%2Fblogic.git

hso: Fix URB submission -EINVAL.

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
