Subject[PATCH 12/12] atm: idt77252: constify pci_device_id.
Date
pci_device_id are not supposed to change at runtime. All functions
working with pci_device_id provided by <linux/pci.h> work with
const pci_device_id. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
27702 468 16 28186 6e1a drivers/atm/idt77252.o

File size After adding 'const':
text data bss dec hex filename
27766 404 16 28186 6e1a drivers/atm/idt77252.o
