ata: libata-scsi: ignore reserved bits for REPORT SUPPORTED OPERATION CODES
commit 3ef600923521616ebe192c893468ad0424de2afb upstream.
For REPORT SUPPORTED OPERATION CODES command, the service action field is
defined as bits 0-4 in the second byte in the CDB. Bits 5-7 in the second
byte are reserved.
Only look at the service action field in the second byte when determining
if the MAINTENANCE IN opcode is a REPORT SUPPORTED OPERATION CODES command.
This matches how we only look at the service action field in the second
byte when determining if the SERVICE ACTION IN(16) opcode is a READ
CAPACITY(16) command (reserved bits 5-7 in the second byte are ignored).
