It can be found that platform_get_irq() returns nagative code but not

s/null/zero/?
The comment of the platform_get_irq clearly shows that.
This comment still doesn't correspond to reality -- 0 can be returned
(although this would cause a WARN() call)...
Therefore it should be better to remove the useless check.
This patch is correct but premature. I have a (not yet merged) patch:
https://marc.info/?l=linux-kernel&m=163623041902285
It actually disables reporting IRQ0. Until it's merged we have to filter
out IRQ0 in the libata drivers as libata treats 0 as an indication of the
polling mode...
