From 00990e7ce0b0e596fe41d9c64d6933ea70084003 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Fri, 30 Jul 2010 13:13:46 +0200 Subject: pcmcia: use autoconfiguration feature for ioports and iomem When CONF_AUTO_SET_IO or CONF_AUTO_SET_IOMEM are set, the corresponding fields in struct pcmcia_device *p_dev->resource[0,1,2] are set accordinly. Drivers wishing to override certain settings may do so in the callback function, but they no longer need to parse the CIS entries stored in cistpl_cftable_entry_t themselves.
