[PATCH] SCSI: userspace cannot use scsi_command_size_tbl, COMMAND_SIZE and scsi_device_type

[Jaswinder Singh Rajput <jaswinder@kernel.org>]

userspace cannot use scsi_command_size_tbl, COMMAND_SIZE
and scsi_device_type defined in kernel

fix the following 'make headers_check' warnings:

  usr/include/scsi/scsi.h:159: userspace cannot call function or variable defined in the kernel
  usr/include/scsi/scsi.h:285: userspace cannot call function or variable defined in the kernel
