From 5f513e1197f27e9a0bcfec0feaac59f976f4a37e Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Thu, 19 Mar 2009 10:01:47 +0100 Subject: [PATCH] ALSA: pcm - Reset invalid position even without debug option Always reset the invalind hw_ptr position returned by the pointer callback. The behavior should be consitent independently from the debug option. Also, add the printk_ratelimit() check to avoid flooding debug prints.
