Subject: [PATCH] USB: gadget: storage: reuse definitions from scsi.h header file
From: Michal Nazarewicz <mina86@...a86.com>
This commit changes storage_common.h, file_storage.c and
f_mass_storage.c to use definitions of SCSI commands from
scsi/scsi.h file instead of redefining the commands in
storage_common.c.
scsi/scsi.h header file was missing READ_FORMAT_CAPACITIES and
READ_HEADER so this commit also add those to the header.
