+ if (uport) + spin_lock_irqsave(&uport->lock, flags);That's the same thing as just calling uart_port_lock(), why aren't you doing that?Because the compiler can't seem to "see" through the macros/ref calls, and I get the warning I mentioned here if I use them: https://lkml.org/lkml/2018/7/6/840
What horrible version of gcc are you using that give you that? Don't open-code things just because of a broken compiler. thanks, greg k-h
