From 4769bfb9dada678b31a2ec275372624dbfeed9d1 Mon Sep 17 00:00:00 2001 From: Samuel Holland Date: Wed, 4 Mar 2020 23:11:41 -0600 Subject: ALSA: pcm: Add a standalone version of snd_pcm_limit_hw_rates It can be useful to derive min/max rates of a snd_pcm_hardware without having a snd_pcm_runtime, such as before constructing an ASoC DAI link. Create a new helper that takes a pointer to a snd_pcm_hardware directly, and refactor the original function as a wrapper around it, to avoid needing to update any call sites.
