Subject: [PATCH] pcmcia (3/4): convert ds.c's socekt_info_t to struct pcmcia_bus_socket
Date: Tue, 25 Mar 2003 20:37:28 +0100 [thread overview]
Message-ID: <20030325193728.GC15319@brodo.de> (raw)
Rename socket_info_t (which is used many, many times differently
within pcmcia) to "struct pcmcia_bus_socket".
Also, a couple of functions in ds.c can be converted to use the "struct
pcmcia_bus_socket" as argument instead of the socket number.
