From cdb138080b78146d1cdadba9f5dadbeb97445b91 Mon Sep 17 00:00:00 2001 From: Dominik Brodowski Date: Wed, 28 Jul 2010 10:59:06 +0200 Subject: pcmcia: do not use win_req_t when calling pcmcia_request_window() Instead of win_req_t, drivers are now requested to fill out struct pcmcia_device *p_dev->resource[2,3,4,5] for up to four iomem ranges. After a call to pcmcia_request_window(), the windows found there are reserved and may be used until pcmcia_release_window() is called.
