From c75b0476245ad01306e4ea510bb3f7591767079f Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 31 Jan 2017 15:49:15 +0100 Subject: ALSA: x86: Replace pr_xxx() with dev_xxx() dev_xxx() helpers give a tidier output in general. While we're at it, remove many useless debug prints (e.g. the ones at each function entry), replace some too verbose errors with debugs, and use WARN_ON() for some serious errors.
