From e6c2e7eb27fc512af6875d7f2cf313e29c61be0b Mon Sep 17 00:00:00 2001 From: Lars-Peter Clausen Date: Fri, 24 May 2013 15:18:10 +0200 Subject: ALSA: Constify the snd_pcm_substream struct ops field The ops field of the snd_pcm_substream struct is never modified inside the ALSA core. Making it const allows drivers to declare their snd_pcm_ops struct as const.
