The patch ASoC: SOF: topology: use set_get_data in process load has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4 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 cac974a51ebb955f3be260a9633836e1413c8672 Mon Sep 17 00:00:00 2001 From: Jaska Uimonen <jaska.uimonen@xxxxxxxxx> Date: Fri, 9 Aug 2019 18:17:14 -0500 Subject: [PATCH] ASoC: SOF: topology: use set_get_data in process load Currently when loading sof process components there's a check if binary control data is associated with it. If found the data is extracted to be part of component loading and initialization. If binary data exceeds the ipc max size, loading fails with error as large message support is only implemented in set_get_data method. So make the process loading use set_get_data to enable large parameters in component initialization. Also refactor the process component loading function as it digs out 3 times almost identical information of related controls. This is redundant, looks ugly and makes it difficult to understand the mechanism. So make a function out of fetching the control data and use it in process loading.
