From 07f8569fbe44f35e53c7a5946fbb348432c68377 Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Sun, 4 Oct 2020 21:32:00 +0200 Subject: w1: Constify struct w1_family_ops The fops field in the w1_family struct is never modified. Make it const to indicate that. Constifying the pointer makes it possible for drivers to declare static w1_family_ops structs const, which in turn will allow the compiler to put it in read-only memory.
