Subject: [PATCH] media: go7007: Constify static struct snd_device_ops
Date: Wed, 26 Jan 2022 00:46:02 +0100 [thread overview]
Message-ID: <20220125234602.10481-1-rikard.falkeborn@gmail.com> (raw)
The only usage of go7007_snd_device_ops is to pass its address to
snd_device_new() which takes a pointer to const struct snd_device_ops.
Make it const to allow the compiler to put it in read-only memory.
