[alsa-devel] [PATCH 1/3] ASoC: ti: remove compat dma probing
After running into a link error:
sound/soc/ti/edma-pcm.o:(.rodata+0x18): undefined reference to `edma_filter_fn'
I checked all users of this, and they have new-style 'dma_slave_map' tables, so none of them should still need it. Removing the associated lines simplifies the code and avoids the build-time dependency on the respective dmaengine drivers.
Acked-by: Peter Ujfalusi peter.ujfalusi@ti.com Signed-off-by: Arnd Bergmann arnd@arndb.de --- v2: remove header inclusions as well
I added the two dmaengine patches to the series this time, but we probably want to have those merged separately through the dmaengine tree, while this one should get merged as a bugfix through ASoC. --- sound/soc/ti/edma-pcm.c | 5 +---- sound/soc/ti/sdma-pcm.c | 9 +++------ 2 files changed, 4 insertions(+), 10 deletions(-)

The patch
ASoC: ti: remove compat dma probing
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: Arnd Bergmann arnd@arndb.de Date: Thu, 7 Mar 2019 16:16:08 +0100 Subject: [PATCH] ASoC: ti: remove compat dma probing
After running into a link error:
sound/soc/ti/edma-pcm.o:(.rodata+0x18): undefined reference to `edma_filter_fn'
I checked all users of this, and they have new-style 'dma_slave_map' tables, so none of them should still need it. Removing the associated lines simplifies the code and avoids the build-time dependency on the respective dmaengine drivers.
