After removing the first hunk, this works fine on r8a7791/koelsch.
The following warnings are no longer seen:

    WARNING: CPU: 0 PID: 1 at drivers/i2c/i2c-core.h:41 i2c_transfer+0x80/0xf8
    No atomic I2C transfer handler for 'i2c-6'
    ...
    WARNING: CPU: 0 PID: 1 at kernel/sched/core.c:1731 set_task_cpu+0xf4/0x1fc

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
