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 75bd90860a1f6d4671403f5b7beb9c4430ca9750 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Fri, 16 Jun 2017 11:20:29 +0200 Subject: [PATCH] ASoC: intel: Use kvzalloc() for suspend buffers Intel SST driver allocates lots of pages at suspend for saving the firmware states, and this may occasionally lead to the allocation error due to the high order, ending up with the suspend failure. Use kvzalloc() so that it can fall back to vmalloc() gracefully.
