Subject[PATCH 3/3] infiniband: pvrdma: 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
10774 1872 8 12654 316e infiniband/hw/vmw_pvrdma/pvrdma_main.o

File size After adding 'const':
text data bss dec hex filename
10838 1808 8 12654 316e infiniband/hw/vmw_pvrdma/pvrdma_main.o
