[PATCH] mmc: host: via-sdmmc: constify pci_device_id.

From: Arvind Yadav
Date: Mon Jul 17 2017 - 12:31:50 EST


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
6952 880 0 7832 1e98 drivers/mmc/host/via-sdmmc.o

File size After adding 'const':
text data bss dec hex filename
7032 800 0 7832 1e98 drivers/mmc/host/via-sdmmc.o
