From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Don't populate the const read-only arrays spi_test_unit_ready and
spi_test_unit_ready on the stack but instead make them static. Makes the
object code smaller by over 100 bytes:
Before:
text data bss dec hex filename
40171 12832 128 53131 cf8b drivers/scsi/scsi_transport_spi.o
After:
text data bss dec hex filename
39922 12976 128 53026 cf22 drivers/scsi/scsi_transport_spi.o
(gcc version 7.2.0 x86_64)
