The patch ASoC: samsung: i2s: Fix secondary platform device unregistration has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 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 022c4156697b9ae30a00f5cd7cee08ed61554e86 Mon Sep 17 00:00:00 2001 From: Sylwester Nawrocki <s.nawrocki@xxxxxxxxxxx> Date: Tue, 19 Feb 2019 16:19:40 +0100 Subject: [PATCH] ASoC: samsung: i2s: Fix secondary platform device unregistration This fixes unregistration of the secondary platform device so all resources are properly released. Additionally the removal sequence is corrected so it is in reverse order comparing to probe sequence. The test against NULL priv->pdev_sec is removed as it is not necessary.
