[PATCH] pcmcia: resource handling fixes
- properly bail out in set_cis_map if call to socket driver's set_mem_map failed - don't abort do_mem_probe cycle if one entry failed (!CONFIG_PCMCIA_PROBE) - don't do iomem probing in chunks larger than 0x800000 (1 << 23) as yenta_socket and vrc4173_cardu.c fail to set_mem_map for windows equal to or larger than (1 << 24).
