I'm counting about seven different definitions of "GPIO" in the kernel
already.
drivers/hwmon/it87.c:
#define GPIO 0x07
drivers/media/dvb/dvb-usb/ec168.h:
GPIO = 0x04,
drivers/net/hamachi.c:
GPIO=0x6E
drivers/staging/rtl8187se/r8180_hw.h:
#define GPIO 0x91
etcetera. It's a crazy identifier to use in a header file, and
the chances of a miscompile-causing collision are increasing.
enum cd_type {
CD_TYPE_NON_GPIO = 0,
CD_TYPE_GPIO = 1,
};
perhaps?
