Subject[PATCH] staging: atomisp: mt9m114: constify acpi_device_id.
Date
acpi_device_id are not supposed to change at runtime. All functions
working with acpi_device_id provided by <acpi/acpi_bus.h> work with
const acpi_device_id. So mark the non-const structs as const.

File size before:
text data bss dec hex filename
15148 2640 8 17796 4584
drivers/staging/media/atomisp/i2c/mt9m114.o

File size After adding 'const':
text data bss dec hex filename
15244 2512 8 17764 4564
drivers/staging/media/atomisp/i2c/mt9m114.o
