[alsa-devel] [PATCH 02/11] ASoC: Intel: Skylake: Fix delay wrap condition

[Vinod Koul]

From: Guneshwor Singh <guneshwor.o.singh at intel.com>

When delay reported by HW is equal to buffersize, it means the
value is wrapped so we should report as 0. So add the condition
to check this while reporting the delay from LPIB.
