dev_pm_ops are not supposed to change at runtime. All functions
working with dev_pm_ops provided by <linux/device.h> work with const
dev_pm_ops. So mark the non-const structs as const.
File size before:
text data bss dec hex filename
17956 1456 8 19420 4bdc drivers/scsi/ibmvscsi/ibmvscsi.o
File size After adding 'const':
text data bss dec hex filename
18164 1264 8 19436 4bec drivers/scsi/ibmvscsi/ibmvscsi.o
