[-- Attachment #1.1: Type: text/plain, Size: 522 bytes --]
This patch adds poll support to the b44 driver to allow netconsole
support. Style lifted straight from 8139too.c
here is the dmesg output with it in place:
netconsole: device eth0 not up yet, forcing it
netconsole: carrier detect appears flaky, waiting 10 seconds
b44: eth0: Link is down.
b44: eth0: Link is up at 100 Mbps, full duplex.
b44: eth0: Flow control is on for TX and on for RX.
netconsole: network logging started
output confirmed by netcat on other system.

Aside from this bizarre whitespace convention and neglecting to cc:
me, looks good.

sorry,sorry,thanks.
Can you explain where I went wrong in the whitespace so I don't make the
same mistake again? It looked pretty standard to me.
Should I nudge akpm with this or will it go via another route?
Cheers,

Stray space between b44_interrupt and args.

Jeff Garzik usually picks up net driver stuff, I think he got this one.

Must have had my eyes closed. Trivial cleanup patch attached, thanks.
