Subject: [PATCH] media: staging: atomisp: ov2680: constify acpi_device_id
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:

File size After adding 'const':
