The patch ASoC: sprd: Fix return value check in sprd_mcdt_probe() has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.2 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 >From 7c88b92816dfe5eab224b96577b50ac00b4be68a Mon Sep 17 00:00:00 2001 From: Wei Yongjun <weiyongjun1@xxxxxxxxxx> Date: Mon, 29 Apr 2019 12:25:12 +0000 Subject: [PATCH] ASoC: sprd: Fix return value check in sprd_mcdt_probe() In case of error, the function devm_ioremap_resource() returns ERR_PTR() and never returns NULL. The NULL test in the return value check should be replaced with IS_ERR().
