Greg,

Per discussion, a revised patch. Silly me, the value was already
initialized in drivers/pci/probe.c and I'd been dragging along
a prehistoric version of the if checks.

[PATCH 1/2]: define inline for test of pci channel error state

Add very simple routine to indicate the pci channel error state.

care to resend 2/2 also?  It's best to resend entire series, otherwise I
have to go dig for it, and it will take me a while to remember to do
that...

ACK, thanks Linas.

If it doesn't get picked up I can stack it on my queue for netdev later.

why not write this so that it reads:

iow are we assuming that there are multiple error_state's per pdev? That seems bogus.
