[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.
