Hi Samuel,

After merging the mfd tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/gpio/janz-ttl.c: In function 'ttl_probe':
drivers/gpio/janz-ttl.c:158: error: implicit declaration of function 'kzalloc'
drivers/gpio/janz-ttl.c:158: warning: assignment makes pointer from integer without a cast
drivers/gpio/janz-ttl.c:210: error: implicit declaration of function 'kfree'

Caused by commit 989b68d7d885a45099126e32b46304afd9b3789e ("gpio: Add
support for Janz VMOD-TTL Digital IO module") interacting with commit
de380b55f92986c1a84198149cb71b7228d15fbd ("percpu: don't implicitly
include slab.h from percpu.h").

I applied the following fix patch for today.
