[PATCH] powerpc/macintosh: constify wf_sensor_ops structures
From: Julia Lawall <hidden>
Date: 2017-08-02 21:27:11
The wf_sensor_ops structures are only stored in the ops field of a
wf_sensor structure, which is declared as const. Thus the
wf_sensor_ops structures themselves can be const.
Done with the help of Coccinelle.
