The patch ASoC: SOF: Fix probe point getter has been applied to the asoc tree at https://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 a3b7343e3f8c4c74516df41827b6d81905e346a1 Mon Sep 17 00:00:00 2001 From: Cezary Rojewski <cezary.rojewski@xxxxxxxxx> Date: Mon, 9 Mar 2020 15:21:24 +0100 Subject: [PATCH] ASoC: SOF: Fix probe point getter Firmware API changes which introduced 'num_elems' param in several probe structs such as sof_ipc_probe_dma_add_params also impacted getter for both, DMA and probe points. All struct handlers except for sof_ipc_probe_info_params have been updated. Align said handler too to calculate payload size correctly.
