[alsa-devel] [PATCH 03/10] ALSA: control: Use standard printk helpers
Takashi Iwai

Wed Feb 12 12:33:05 CET 2014
Use dev_err() & co as much as possible. If not available (no device
assigned at the calling point), use pr_xxx() helpers instead.
For simplicity, introduce new helpers for pcm stream, pcm_err(), etc.
