[PATCH 0/3] constify drm i2c_device_id

[PATCH 0/3] constify drm i2c_device_id

[Arvind Yadav]

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

All applied.

btw I think this isn't your first series, and we're trying to keep some of
the trivial mistakes around in drm, as an easy way for newbies to get into
the subsystem with their first patch.

We'd like more regular contributors to tackle some of the more involved
cleanup tasks, which should also be more valuable to the subsystem:
