Subject: [PATCH 1/2] soundwire: amd: fix for clearing command status register
Date: Fri, 20 Jun 2025 15:55:19 +0530	[thread overview]
Message-ID: <20250620102617.73437-1-Vijendar.Mukunda@amd.com> (raw)

To clear the valid result status, 1 should be written to
ACP_SDW_IMM_CMD_STS register. Update the ACP_SW_IMM_CMD_STS register value
as 1.

Fixes: d8f48fbdfd9a ("soundwire: amd: Add support for AMD Manager driver")
