[PATCH] powerpc/macintosh: constify wf_sensor_ops structures

From: Julia Lawall
Date: Wed Aug 02 2017 - 17:27:16 EST


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.
