Hello,

It looks like you need to add vintf driver by yourself or if you have driver is incompatible with the kernel version that android 12 have.

Thank you @Bio_TICFSL for the reply.

This error occur with modified defconfig. I added my defconfig in automation_defconfig, with that there is no error.
