Subject: [PATCH 6/8] ASoC: core: Replace sprintf() with sysfs_emit()
Date: Mon,  1 Aug 2022 19:01:06 +0200	[thread overview]
Message-ID: <20220801170108.26340-7-tiwai@suse.de> (raw)
In-Reply-To: <20220801170108.26340-1-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 the sprintf()
usage straightforwardly with a new helper, sysfs_emit().
