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 f1b28110be591426ee9d0f36888fef4e37d707a9 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Mon, 26 Oct 2015 08:41:53 +0000 Subject: [PATCH] ASoC: rsnd: avoid pointless loop in rsnd_mod_interrupt() Current Renesas sound driver doesn't have 1:1 relationship between stream <-> mod because it is supporting MIX. Because of this reason rsnd_mod_interrupt() is searching correspond mod by for loop. But this loop is not needed, because each mod has own type. This patch avoid pointless loop by using mod->type. This patch is good for SSI-parent support, because stream might have 2 SSI as SSI-parent/child. SSI interrupt handler will be called twice if stream has SSI-parent without this patch.
