Update stream irq handler definition to correctly set hdac_stream current position when servicing stream interrupts for compress streams.
Signed-off-by: Cezary Rojewski cezary.rojewski@intel.com ---
Changes in v5: - Addressed u64/ u32 concerns from Pierre when calculating bytes transferred during runtime: div_u64_rem replaced by div64_u64_rem for hda_dsp_set_bytes_transferred and all local variables and hdac_stream::curr_pos are now of u64 type
