[alsa-devel] [PATCH 2/2] ASoC: SOF: Intel: fix reset of host_period_bytes

From: Marcin Rajwa <marcin.rajwa at linux.intel.com>

This patch prevents the reset of host period bytes.
The parameter has been used to keep information about
completion of period copy. Right now we keep this
information in period_irq.
