The patch ASoC: soc-core: add for_each_rtd_components() and replace has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5 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 2b544dd7b43b19fb55ea4fbb3e30b60eb20b7828 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Tue, 15 Oct 2019 12:59:31 +0900 Subject: [PATCH] ASoC: soc-core: add for_each_rtd_components() and replace ALSA SoC has for_each_rtdcom() which is link list for rtd-component which is called as rtdcom. The relationship image is like below rtdcom rtdcom rtdcom component component component rtd->component_list -> list -> list -> list ... Here, the pointer get via normal link list is rtdcom, Thus, current for_each loop is like below, and need to get component via rtdcom->component for_each_rtdcom(rtd, rtdcom) { component = rtdcom->component; ... } but usually, user want to get pointer from for_each_xxx is component directly, like below. for_each_rtd_component(rtd, rtdcom, component) { ... } This patch expands list_for_each_entry manually, and enable to get component directly from for_each macro. Because of it, the macro becoming difficult to read, but macro itself becoming useful.
