Subject[PATCH 12/12] power: reset: account for const type of of_device_id.data
Date
This driver creates a const structure that it stores in the data
field of an of_device_id array.

Add const to the declaration of the location that receives a value
from the data field to ensure that the compiler will continue to check
that the value is not modified and remove the const-dropping cast on
the access to the data field.

Done using Coccinelle.
