From 852801417a89375c0df4285e60d90c7821a1d730 Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Tue, 22 Nov 2016 11:29:14 +0100 Subject: [PATCH] ASoC: Make return type of dpcm_state_string() const char * dpcm_state_string() returns a pointer to a string literal. Modifying a string literal causes undefined behaviour. So make the return type of the function const char * to make it explicit that the returned value should not be modified. This patch is purely cosmetic, none of the users of dpcm_state_string() attempt to modify the returned content.
