Subject: [PATCH 2/4] ALSA: pcm: Make snd_pcm_limit_hw_rates take hw directly
Date: Thu, 13 Feb 2020 00:11:45 -0600
Message-ID: <20200213061147.29386-3-samuel@sholland.org> (raw)
In-Reply-To: <20200213061147.29386-1-samuel@sholland.org>

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.

Since snd_pcm_limit_hw_rates only uses runtime->hw, it does not actually
need the snd_pcm_runtime. Modify it to take a pointer to hw directly.
