Subject: [PATCH 5/7] ALSA: pcm: Replace sprintf() with sysfs_emit()
Date: Mon, 1 Aug 2022 18:56:37 +0200 [thread overview]
Message-ID: <20220801165639.26030-6-tiwai@suse.de> (raw)
In-Reply-To: <20220801165639.26030-1-tiwai@suse.de>
For sysfs outputs, it's safer to use a new helper, sysfs_emit(),
instead of the raw sprintf() & co. This patch replaces such a
sprintf() call straightforwardly with the new helper.
