Subject[PATCH] staging: atomisp: gc0310: 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 After adding 'const':
text data bss dec hex filename
10361 1824 0 12185 2f99 drivers/staging/media/atomisp/i2c/gc0310.o
