Subject[PATCH] char/random: include <linux/hw_random.h> for add_hwgenerator_randomness
Date
The add_hwgenerator_randomness() is declared in <linux/hw_random.h>
but this is not being included in drivers/char/random.c so fix
the following sparse warning by including it:

drivers/char/random.c:2489:6: warning: symbol 'add_hwgenerator_randomness' was not declared. Should it be static?
