Hi,

Please ignore this patch. It breaks the build.

Thank you

If one were to run the handy-dandy command "git grep
add_hwgenerator_randomness", one would find:

drivers/char/hw_random/core.c:          add_hwgenerator_randomness((void *)rng_fillbuf, rc,
drivers/char/random.c:void add_hwgenerator_randomness(const char *buffer, size_t count,
drivers/char/random.c:EXPORT_SYMBOL_GPL(add_hwgenerator_randomness);
drivers/net/wireless/ath/ath9k/rng.c:           add_hwgenerator_randomness((void *)rng_buf, bytes_read,
include/linux/hw_random.h:extern void add_hwgenerator_randomness(const char *buffer, size_t count, size_t entropy);

So the claim that it is only declared in drivers/char/random.c is not
true.

And of course, build-testing patches before sending them out for
review is a really good idea.
