This patch fixes a minor regression introduced in v3.8-rc1 code
where a zero-length INQUIRY was no longer returning the correct
INVALID FIELD IN CDB additional sense code.
This regression was introduced with the following commit:
commit de103c93af
Author: Christoph Hellwig <hch@lst.de>
Date: Tue Nov 6 12:24:09 2012 -0800
target: pass sense_reason as a return value
and this patch has been tested with the following zero-length CDB:
sg_raw /dev/sdd 12 00 83 00 00 00
SCSI Status: Check Condition
Sense Information:
Fixed format, current; Sense key: Illegal Request
Additional sense: Invalid field in cdb
