The patch

   ASoC: SOF: Intel: bdw: Use generic function for fw ready / mem windows creation

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4

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

Subject: [PATCH] ASoC: SOF: Intel: bdw: Use generic function for fw ready /
 mem windows creation

bdw_get_windows / bdw_fw_ready is identical with the generic
implementation introduced in a previous patch.

So remove bdw_get_windows / bdw_fw_ready and use the generic
sof_get_windows version.

Do not forget to implement get_mailbox_offset/get_window_offset
so that we export the correct mailbox/memory window offset to
the outside world.
