It turns out MODULE_DEVICE_TABLE is _really_ preprocessed away. See
include/linux/module.h:
#ifdef MODULE
/* Creates an alias so file2alias.c can find device table. */
#define MODULE_DEVICE_TABLE(type, name) \
extern const typeof(name) __mod_##type##__##name##_device_table \
__attribute__ ((unused, alias(__stringify(name))))
#else /* !MODULE */
#define MODULE_DEVICE_TABLE(type, name)
#endif
Did I get that right?
(I knew the other three MODULE_* macros are handled in slightly more
complicated way, but the effect is basically that they are preprocessed
away.)
