The patch
ASoC: SOF: Intel: hda: remove unnecessary ROM IPC filter function
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

The HDA_DSP_IPC_PURGE_FW IPC from ROM is already handled in cl_dsp_init(), and as IPC IRQ is disabled at this stage, this IPC will be never received in the IRQ thread. The function hda_dsp_ipc_is_sof for filtering the ROM IPC can be removed safely.
