Remove workqueue of flush work in rt1015 driver since we don't need it
after internal discussion, and there is no impact on performance
without this workqueue.

Thanks!

[1/1] ASoC: rt1015: Remove unnecessary flush work on rt1015 driver
      commit: bc1c8e4eee79646b9ae10ededed06a569c7c2bc9

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
