Revision ae2d1f2f5b59d00b39283c52dc4ee675397bbacd authored by Jim Cromie on 14 July 2006, 07:24:16 UTC, committed by Linus Torvalds on 15 July 2006, 04:53:53 UTC 
[PATCH] scx200_gpio: 1 cdev for N minors: cleanup, prep
 
this patch is mostly cleanup of scx200_gpio :
- drop #include <linux/config.h>
- s/DEVNAME/DRVNAME/    apparently a convention
- replace variable num_pins with  #define MAX_PINS
- s/dev/devid/   to clarify that its a dev_t, not a struct device dev.
- move devid = MKDEV(major,0)  into branch where its needed.

2 minor 'changes' :

- reduced MAX_PINS from 64 to 32.  Ive never tested other pins, and
  theyre all multiplexed with other functions, some of which may be in use
  on my soekris 4801, so I dont know what testing should yield.

- +EXPORT_SYMBOL(scx200_access);

  This exposes the driver's vtable, which another driver can use along
  with #include <linux/nsc_gpio.h>, to manipulate a gpio-pin.
