This patch converts the drivers in drivers/pcmcia/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

/* This is a fairly generic PCMCIA socket driver suitable for the
|
|
* following Alchemy Development boards:
|
|
* Db1000, Db/Pb1500, Db/Pb1100, Db/Pb1550, Db/Pb1200, Db1300
|
|
*
|
|
* The Db1000 is used as a reference: Per-socket card-, carddetect- and
|
|
* statuschange IRQs connected to SoC GPIOs, control and status register
|
|
* bits arranged in per-socket groups in an external PLD. All boards
|
|
* listed here use this layout, including bit positions and meanings.
|
|
* Of course there are exceptions in later boards:
|
|
*
|
|
* - Pb1100/Pb1500: single socket only; voltage key bits VS are
|
|
* at STATUS[5:4] (instead of STATUS[1:0]).
|
|
* - Au1200-based: additional card-eject irqs, irqs not gpios!
|
|
* - Db1300: Db1200-like, no pwr ctrl, single socket (#1).
