[PATCH] WAN: ioremap() failure checks in drivers
Eric Sesterhenn found that pci200syn initialization lacks return statement in ioremap() error path (coverity bug id #195). It looks like more WAN drivers have problems with ioremap(). Signed-off-by: Krzysztof Halasa <khc@pm.waw.pl> Signed-off-by: Jeff Garzik <jeff@garzik.org>
