'struct i2c_device_id' is not modified in these drivers.
Constifying this structure moves some data to a read-only section, so
increase overall security.
On a x86_64, with allmodconfig, as an example:
Before:
======
text data bss dec hex filename
15566 987 32 16585 40c9 drivers/gpu/drm/bridge/chipone-icn6211.o
After:
=====
text data bss dec hex filename
15630 923 32 16585 40c9 drivers/gpu/drm/bridge/chipone-icn6211.o
