[PATCH] scsi: remove volatile from scsi data
This patch removes volatile qualifier from scsi_device->device_busy,
Scsi_Host->host_busy and ->host_failed as the volatile qualifiers
don't serve any purpose now. While at it, convert those fields from
unsigned short to unsigned int as suggested by Christoph.
