[PATCH] staging: atomisp: gc0310: constify acpi_device_id.

[Arvind Yadav]

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
  10297    1888       0   12185    2f99 
drivers/staging/media/atomisp/i2c/gc0310.o

File size After adding 'const':
   text    data     bss     dec     hex filename
  10361    1824       0   12185    2f99
