From d3c36ed8e578185b752dac4277819965fa5f6879 Mon Sep 17 00:00:00 2001 From: Adrian Knoth Date: Fri, 5 Jul 2013 11:28:09 +0200 Subject: ALSA: hdspm - Introduce hdspm_get_aes_sample_rate() Helper function to return the AES sample rate class. This class needs to be translated via HDSPM_bit2freq() to get the more common representation.
