[PATCH] char: add missing header dependencies
From: Baoyou Xie
Date: Thu Sep 01 2016 - 06:41:35 EST
We get 1 warning when building kernel with W=1:
drivers/char/random.c:2126:6: warning: no previous prototype for 'add_hwgenerator_randomness' [-Wmissing-prototypes]
In fact, this function is declared in include/linux/hw_random.h,
so this patch adds missing header dependencies.
