[BUG] Kernel crash on Allwinner H3 due to sound core changes

Hi all,

with todays linux-next (next-20180228), kernel on Allwinner H3 SoC crashes
with dmesg like that: https://pastebin.com/raw/0D5JeaJ8

I bisected the kernel and first offending commit is:
be7ee5f32a9a ("ASoC: soc-generic-dmaengine-pcm: replace platform to
component")

I know that crash message is completely unrelated to sound subsystem, but it
turns out that if I disable CONFIG_SND_SUN4I_CODEC kernel works ok, but this
way I lose analog audio output.

Any suggestions what can be the issue?

Best regards,
Jernej
