[PATCH] ASoC: imx-pcm-rpmsg: Remove unused variable

[Deepak R Varma]

Variable ret is initialed but is never modified or used except for
returning the initial value 0. The value can be directly returned
instead and the variable definition can be dropped.
Issue identified using returnvar.cocci Coccinelle semantic patch.

[1/1] ASoC: imx-pcm-rpmsg: Remove unused variable
      commit: 88541443497d47313ec4de1ecc1946288ae0ed16

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
