[PATCH v2 50/57] irqdomain: Use irq_domain_instantiate() retvals as initializers

[Jiri Slaby (SUSE)]

I was thinking whether add a \n before the 'return' or this. And this
looks both more compact and more readable.

Note irq_domain_create_hierarchy()'s handling of size is now part of
info's initializer (using the ternary operator). That makes more sense
while reading it.
