[PATCH 4/4] scsi: scsi_transport_spi: constify attribute_group structures.

From: Arvind Yadav
Date: Fri Jul 14 2017 - 04:24:27 EST


attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/attribute_container.h>
and <linux/sysfs.h> work with const attribute_group. So mark the non-const
structs as const.

File size before:
text data bss dec hex filename
15444 1616 0 17060 42a4 drivers/scsi/scsi_transport_spi.o

File size After adding 'const':
text data bss dec hex filename
15572 1488 0 17060 42a4 drivers/scsi/scsi_transport_spi.o
