This patch adds removing of extra zeros in the FIR coefficients. The zeros can happen in some responses due to fixed point quantization of very small values. The zero taps consume DSP resources for nothing so better to clean them out for EQ configuration data. Signed-off-by: Seppo Ingalsuo <seppo.ingalsuo@linux.intel.com>
