Subject[PATCH] nfc: nxp-nci: 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
2208 400 0 2608 a30 drivers/nfc/nxp-nci/i2c.o

File size After adding 'const':
text data bss dec hex filename
2272 336 0 2608 a30 drivers/nfc/nxp-nci/i2c.o
