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. Signed-off-by: Roel Kluin <roel.kluin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
