depca: fix warning in drivers/net/depca.c
fix warning: drivers/net/depca.c: In function ‘depca_eisa_probe’: drivers/net/depca.c:1564: warning: ‘mem_start’ may be used uninitialized in this function this seems to be a real bug - depca_eisa_probe() does not check for failure. Add it, symmetric to depca_isa_probe(). Signed-off-by: Ingo Molnar <mingo@elte.hu> Signed-off-by: David S. Miller <davem@davemloft.net>
