Subject: [PATCH] ASoC: SOF: sof-probes: Constify sof_probe_compr_ops
Date:   Sat,  4 Dec 2021 21:32:20 +0100
Message-Id: <20211204203220.54712-1-rikard.falkeborn@gmail.com>
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The only usage of sof_probe_compr_ops is to assign its address to the
cops field in the snd_soc_dai_driver struct (in
sound/soc/sof/intel/hda-dai.c). Make it const to allow the compiler to
put it in read-only memory.
