Hi,

yesterday i was testing with Linux 5.13-rc3 on my Raspberry Pi 4 B
(multi_v7_defconfig) and i'm getting the following errors during boot:

[   25.947494] vc4_hdmi fef00700.hdmi: ASoC: error at

Rootfs: Raspberry Pi OS 32 bit (April 2021)

But according to aplay -l both hdmi devices have been registered. Does
anyone have seen this, too?
