Subject: [PATCH] sound/hda: rate-limit timeout message
Date: Mon, 31 Oct 2005 13:20:02 -0800 [thread overview]
Message-ID: <20051031132002.14b7aedb.randy_d_dunlap@linux.intel.com> (raw)
From: Randy Dunlap <randy_d_dunlap@linux.intel.com>
Rate-limit the azx_get_response timeout message.
A continuous 2 per second is too much.
