[1/8] ASoC: amd: acp: add a null check for chip_pdev structure commit: 98d919dfee1cc402ca29d45da642852d7c9a2301 [2/8] ASoC: amd: acp: remove i2s configuration check in acp_i2s_probe() commit: 70fa3900c3ed92158628710e81d274e5cb52f92b [3/8] ASoC: amd: acp: move chip->flag variable assignment commit: 379bcd2c9197bf2c429434e8a01cea0ee1852316 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. 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

When acp platform device creation is skipped, chip->chip_pdev value will remain NULL. Add NULL check for chip->chip_pdev structure in snd_acp_resume() function to avoid null pointer dereference.
