From 38d89a564847048c0f6fe53a829d15edb4f21da3 Mon Sep 17 00:00:00 2001 From: Rikard Falkeborn Date: Sat, 6 Feb 2021 23:58:49 +0100 Subject: [PATCH] ASoC: fsl: constify static snd_soc_dai_ops structs The only usage of these is to assign their address to the 'ops' field in the snd_soc_dai_driver struct, which is a pointer to const. Make them const to allow the compiler to put them in read-only memory.
