[PATCH 00/15] constify pnp_device_id and pnp_card_device_id

[PATCH 00/15] constify pnp_device_id and pnp_card_device_id

[Arvind Yadav]

*_device_id are not supposed to change at runtime. All functions
working with *_device_id provided by <linux/pnp.h> work with
const *_device_id. So mark the non-const structs as const.
