Old wine in a new bottle with added flavour now.
Based on our discussions in LPC, now we will report the combined delay value as
sum of the buffering done in driver and hardware. This is used to report delay
Additionally we tell pcm what is buffer in device/driver, this is used to check
for error calulcations

Vinod Koul (3):
  ALSA: pcm - introduce device_buffer
  ASoC: add device_buffer in asoc
  ASoC: mid-x86 - implement buffer query in sst_platform driver
