What IRQ domain did you consider? In case of STRICT the mapping will
be 1:1 and 0 is _valid_ IRQ number for hwirq.
0 in Linux kernel IRQ numbering often means NO_IRQ. But there might be
exceptions.

So, it would be nice to see if there is a problem on certain platform
if the patch is not applied, or is it problem on OF IRQ code, or
wrong interpratation of 0?
