EtherExpress16: fix printing timed out status
in drivers/net/eexpress.c:558, function unstick_cu()
while (!SCB_complete(rsst=scb_status(dev))) {
...
if (...)
printk(KERN_WARNING "%s: Reset timed out status %04x, retrying...\n",
dev->name,rsst);
}
but this will become
while (!((rsst = scb_status(dev) & 0x8000) != 0) ...
because of the macro:
#define SCB_complete(s) ((s&0x8000)!=0)
so rsst can only become either 0x8000 or 0, but in the latter case the
loop ends, I think the wrong timed out status is printed. This also
cleans up similar macros.
