[ CC Ted (new random maintainer) ]

Is this due to this change?

Subject: [PATCH] random: remove rand_initialize_irq()

With the new interrupt sampling system, we are no longer using the
timer_rand_state structure in the irq descriptor, so we can stop
initializing it now.

Signed-off-by: "Theodore Ts'o" <tytso@....edu

...looks like AB3100 is the *only* driver still using rand_initialize_irq()...

drivers/mfd/ab3100-core.c:939:  rand_initialize_irq(client->irq);

...but why has random.h still this...?

include/linux/random.h:51:extern void rand_initialize_irq(int irq);

Just thinking "loud"...
