pcmcia: add locking to set_mem_map()
Protect the pccard_operations callback "set_mem_map" by a new mutex ops_mutex. This mutex also protects the following values in struct pcmcia_socket: pccard_mem_map win[] pccard_mem_map cis_mem void __iomem *cis_virt Tested-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net>
