Subject: [PATCH 13/13] ALSA: usb: constify snd_pcm_ops structures
Date: Fri, 18 Aug 2017 13:15:21 +0530	[thread overview]
Message-ID: <a6ce54c995eb3ce68bf6231ccc9a2ccee17ec023.1503040251.git.arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1503042321-26758-1-git-send-email-arvind.yadav.cs@gmail.com>
In-Reply-To: <19589e15b10f062109b5e90c9c253aefb2d3819c.1503040251.git.arvind.yadav.cs@gmail.com>

snd_pcm_ops are not supposed to change at runtime. All functions
working with snd_pcm_ops provided by <sound/pcm.h> work with
const snd_pcm_ops. So mark the non-const structs as const.
