Pass '0' in place of hardcoded "irq_base" value as "first_irq" parameter to
"irq_domain_add_simple" in order to use linear irq domain.

I believe you can safely go with calling irq_domain_add_linear() directly
here.
Otherwise the patch looks good.

Yes, I will replace the call and resend the patch.
