[PATCH V2 1/2] scsi: storvsc: Install the storvsc specific timeout handler for FC devices

From: K. Y. Srinivasan
Date: Wed Jan 27 2016 - 19:46:40 EST


The default timeout routine used for FC transport is not
suitable for FC devices managed by storvsc since FC devices
managed by storvsc driver do not have an rport associated
with them. Use the time out handler used for SCSI devices
for FC devices as well.
