Subject: [PATCH] ASoC: amd: acp6x-pdm-dma: Constify static snd_soc_dai_ops
Date: Sat, 4 Dec 2021 12:08:48 +0100 [thread overview]
Message-ID: <20211204110848.21322-1-rikard.falkeborn@gmail.com> (raw)
The only usage of acp6x_pdm_dai_ops is to assign its address to the ops
field in the snd_soc_dai_driver struct, which is a pointer to const
snd_soc_dai_ops. Make it const to allow the compiler to put it in
read-only memory.
