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 1f8754d4daea5f257370a52a30fcb22798c54516 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Tue, 16 May 2017 01:48:24 +0000 Subject: [PATCH] ASoC: rsnd: don't call free_irq() on Parent SSI If SSI uses shared pin, some SSI will be used as parent SSI. Then, normal SSI's remove and Parent SSI's remove (these are same SSI) will be called when unbind or remove timing. In this case, free_irq() will be called twice. This patch solve this issue.
