Subject: [PATCH 1/7] ALSA: ac97: Replace sprintf() with sysfs_emit()
Date: Mon,  1 Aug 2022 18:56:33 +0200	[thread overview]
Message-ID: <20220801165639.26030-2-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 the open code
straightforwardly with a new helper.
