[PATCH] pcmcia: move PCMCIA ioctl to a separate file
Move all PCMCIA_IOCTL-related code to a different file. Signed-off-by: Dominik Brodowski <linux@dominikbrodowski.net> From: Richard Purdie <rpurdie@rpsys.net> The pcmcia-move-pcmcia-ioctl-to-a-separate-file patch was corrupted in -mm2 causing this problem. Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

- bind_request() and bind_device() are merged by now. Register_client()
- is called right at the end of bind_request(), during the driver's
- ->attach() call. Individual descriptions:
-
- bind_request() connects a socket to a particular client driver.
- It looks up the specified device ID in the list of registered
- drivers, binds it to the socket, and tries to create an instance
- of the device. unbind_request() deletes a driver instance.
-
- Bind_device() associates a device driver with a particular socket.
- It is normally called by Driver Services after it has identified
- a newly inserted card. An instance of that driver will then be
- eligible to register as a client of this socket.
-
- Register_client() uses the dev_info_t handle to match the
- caller with a socket. The driver must have already been bound
- to a socket with bind_device() -- in fact, bind_device()
- allocates the client structure that will be used.
