Applied "ASoC: SOF: Intel: hda: remove unnecessary ROM IPC filter function" to the asoc tree

[Mark Brown]

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.

Subject: [PATCH] ASoC: SOF: Intel: hda: remove unnecessary ROM IPC filter
 function

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.
