A possible compromise: We can have both. We rename platform_get_irq_optional() to platform_get_irq_silent() (or platform_get_irq_silently() if this is preferred) and once all users are are changed (which can be done mechanically), we reintroduce a platform_get_irq_optional() with Sergey's suggested semantic (i.e. return 0 on not-found, no error message printking).
Please do not do that as anyone trying to forward-port an old driver will miss the abi change of functionality and get confused. Make build-breaking changes, if the way a function currently works is changed in order to give people a chance.
Fine for me. I assume this is a Nack for Sergey's patch?
Which patch do you mean? I'm starting to get really muddled... :-(
I'm talking about "[PATCH 1/2] platform: make platform_get_irq_optional() optional" because "trying to forward-port an old driver will miss the abi" applies to it.
Best regards Uwe
