From 55abb59c9a03d3aceda61e97b5ff19d9274fc611 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 23 Apr 2010 10:09:58 +0300 Subject: [PATCH] ASoC: tlv320dac33: Skip calculations in FIFO Bypass mode There is no need for calculations for FIFO bypass mode. Just in case set the nsample maximum limit, which has been done in the calculation phase.
