[PATCH] of: Fix constantness of of_n_size_cells
From: Geoff Levand <hidden>
Date: 2014-08-22 17:43:36
Subsystem:
open firmware and flattened device tree, the rest · Maintainers:
Rob Herring, Saravana Kannan, Linus Torvalds
The of_n_size_cells() routine only does a read-only operation on the device tree
passed in, so add the const keyword to that argument so that of_n_size_cells()
can be called with read-only data without casting.
