When SMC_DEBUG >= 2, we hit the following compilation error:
drivers/net/ethernet/smsc/smc91x.c:85:0:
drivers/net/ethernet/smsc/smc91x.c: In function ‘smc_findirq’:
drivers/net/ethernet/smsc/smc91x.c:1784:9: error: ‘dev’ undeclared (first use in this function)
DBG(2, dev, "%s: %s\n", CARDNAME, __func__);
^
Fix it by passing in the appropriate netdev pointer.

Perhaps verifying the format and args in all cases
would help avoid more of these in the future.

Sounds good. I can add it as the second patch in the series.

How about the following?
Ok to add your Signed-off-by as well?
Thanks.
