I did some digging and it seems that the dpkg-deb - command, fails to
this error when run manually:

dpkg-deb: error: failed to open package info file
'/home/teemu/proj/imx8dev/src/platform/hv/build/tmp/work/imx8qxpmek-poky-linux/linux-imx/4.9.123-r0/packages-split/kernel-module-snd-hwdep-4.9.123-imx_4.9.123_imx8mm_ga+g6a71cbc/DEBIAN/control'
for reading: No such file or directory

How has anyone else managed to build Yocto image for i.MX8? Or has
anyone done that?
