Subject: [PATCH] ALSA: pcm: Replace sprintf() with sysfs_emit()
Git-commit: 01043e3e14d3e17acf563e0ce27abd73c6edde7f
Patch-mainline: v6.0-rc1
References: jsc#PED-850
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.
