From 89930b7b5e3e9bfe9c6ec5e19920451c8f5d9088 Mon Sep 17 00:00:00 2001 From: Denis Joseph Barrow Date: Tue, 25 Nov 2008 00:30:48 -0800 Subject: [PATCH] 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 Signed-off-by: Denis Joseph Barrow Signed-off-by: David S.
