drivers/net/tlan.c: compilation warning fix
Add a check for the pci_register_driver() return value. Removed unused variable pad_allocated. The aim of this patch is to remove the following warning messages: drivers/net/tlan.c: In function 'tlan_probe': drivers/net/tlan.c:486: warning: ignoring return value of 'pci_register_driver', declared with attribute warn_unused_result Signed-off-by: Leonardo Potenza <lpotenza@inwind.it> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Jeff Garzik <jeff@garzik.org>
