    [SERIAL] Fix up 8250 IRQ chain handling · 31efb7f7
    Russell King authored
    - Unlink port from chain if request_irq fails
    - Allow port to define whether we use shared IRQs
      (this is required for PCMCIA serial cards where the serial
       card shares the same IRQ as the socket status IRQ.)
    - Convert remaining ASYNC_ flags to UPF_ flags
