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 a7c439d6128de2cbc087ae7524b47f613ff8bc6c Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 11 Sep 2018 15:50:27 +0900 Subject: [PATCH] ASoC: soc-core: remove dai->driver NULL check It is strange if it has "dai" but doesn't have "dai->driver". And more over "dai->driver->xxx" is used everywhere without "dai->driver" pointer NULL checking. It got Oops already if "dai->driver" was NULL. Let's remove un-needed "dai->driver" NULL check.
