[PATCH 01/22] pcmcia: do not use win_req_t when calling pcmcia_request_window()
Dominik Brodowski
linux at dominikbrodowski.net
Thu Oct 21 11:35:17 EDT 2010
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.

* pcmcia_request_io changes (as of 2.6.36)
Instead of io_req_t, drivers are now requested to fill out
struct pcmcia_device *p_dev->resource[0,1] for up to two ioport
