The patch media: pxa_camera: remove the dmaengine compat need 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 f727b6cda449184188d8a64987f194687bf01782 Mon Sep 17 00:00:00 2001 From: Robert Jarzmik <robert.jarzmik@xxxxxxx> Date: Sun, 17 Jun 2018 19:02:08 +0200 Subject: [PATCH] media: pxa_camera: remove the dmaengine compat need As the pxa architecture switched towards the dmaengine slave map, the old compatibility mechanism to acquire the dma requestor line number and priority are not needed anymore. This patch simplifies the dma resource acquisition, using the more generic function dma_request_slave_channel().
