Subject: [PATCH 4/4] ALSA: cs46xx: Clean up proc file creations
Date: Tue, 5 Feb 2019 17:07:58 +0100 [thread overview]
Message-ID: <20190205160758.9172-5-tiwai@suse.de> (raw)
In-Reply-To: <20190205160758.9172-1-tiwai@suse.de>
Again no functional changes, but only code clean up.
Use a standard macro for initializing the procfs entries, also drop
the info entries stored in dsp_spos_instance, as they are removed
recursively by a single snd_info_free_entry() calls.
