[PATCH] regulator: as3722: Constify regulator ops

From: Thierry Reding
Date: Thu Apr 07 2016 - 10:22:39 EST


A const pointer to regulator ops is stored in regulator descriptors. The
operations never need to be modified, so define them as const as a hint
to the compiler that they can go into .rodata.
