The patch
ASoC: qcom: remove duplicate initializations of dma_ch and v
has been applied to the asoc tree at
git://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

dma_ch is being initialized to zero and then immediately afterwards being updated again, so the first initialization is redundant and can be remove.
Likewise, the pointer v is being initialized twice, so remove the second duplicate initialization.
Cleans up two clang build warnings: warning: Value stored to 'dma_ch' is never read warning: Value stored to 'v' during its initialization is never read
