Thanks for your patch!

This can be a single bit:
unsigned int use_of_thermal : 1;

If you would add feature bits, you can get rid of rcar_thermal_type:
unsigned int has_filonoff : 1;
unsigned int has_enr : 1;
unsigned int needs_suspend_resume : 1;
The number of interrupts can be stored here, too.

I don't think the cast is needed.

when I'm talking to journalists I just say "programmer" or something like that.
