The patch ASoC: rcar: remove rsnd_kctrl_remove() has been applied to the asoc tree at git://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 e0c4211854bfebd5507761a2bfddaa9e37074230 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Tue, 28 Mar 2017 02:31:23 +0000 Subject: [PATCH] ASoC: rcar: remove rsnd_kctrl_remove() Current rcar driver is trying to remove kctrl when remove time. But, 1) rcar driver can't/shouldn't remove before removing sound card driver, 2) sound card driver will call snd_ctl_dev_free() and removes all kctrls by snd_ctl_remove(). Thus, rsnd_kctrl_remove() is not necessary. Current implementation will get Oops when removing rcar driver after sound card. This patch fix this issue.
