I meant that on the other side people who are in favour of Sergey's patch.
Since that I commented already that I opposed the renaming being a standalone
change.

Do you agree that we have several issues with platform_get_irq*() APIs?

1. The unfortunate naming
2. The vIRQ0 handling: a) WARN() followed by b) returned value 0
3. The specific cookie for "IRQ not found, while no error happened" case
