[PATCH 26/26] sgi-xp: constify local structures

From: Julia Lawall
Date: Sun Sep 11 2016 - 09:27:07 EST

For structure types defined in the same file or local header files, find
top-level static structure declarations that have the following
1. Never reassigned.
2. Address never taken
3. Not passed to a top-level macro call
4. No pointer or array-typed field passed to a function or stored in a
Declare structures having all of these properties as const.

Done using Coccinelle.
Based on a suggestion by Joe Perches <joe@xxxxxxxxxxx>.

The semantic patch seems too long for a commit log, but is in the cover
