Subject[2.6 patch] drivers/char/hw_random.c: remove assert()'s
This patch removes the assert()'s from drivers/char/hw_random.c since
you both needed to enable a manual option in the driver source to make
them effective and they only covered some obviously impossible cases.

Signed-off-by: Adrian Bunk <bunk@stusta.de>
