You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >>From 6e56e5d04191aa20e08430dcb203c081fa247e93 Mon Sep 17 00:00:00 2001 From: "Agrawal, Akshu" Date: Thu, 7 Jun 2018 14:48:43 +0800 Subject: [PATCH] ASoC: AMD: Add NULL pointer check Fix crash in those platforms whose machine driver does not expose platform_info. For those platforms we rely on default value and select I2SSP channel.
