True.

I still feel uneasy about pushing false positive error messages to
users. Do you think your cocci-script could be updated to modify drivers
which do not bail out when platform_get_irq() fails to use
platform_get_irq_nowarn()? I'd think this would catch most of them?

Or maybe the other way around? platform_get_irq_warn() and only convert
those which print something?
