[alsa-devel] [PATCH 1/6] ALSA: hda/tegra - Set CORBRP self-clear flag

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

This is set for the MCP variants of the NVIDIA HDA controller, which the
Tegra variant was derived from. This fixes the following warning at boot
time:

	[    2.486610] tegra-hda 70030000.hda: CORB reset timeout#1, CORBRP = 0
