Hi Tejun,

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

drivers/input/misc/pcf8574_keypad.c: In function 'pcf8574_kp_probe':
drivers/input/misc/pcf8574_keypad.c:95: error: implicit declaration of function 'kzalloc'
drivers/input/misc/pcf8574_keypad.c:95: warning: assignment makes pointer from integer without a cast
drivers/input/misc/pcf8574_keypad.c:156: error: implicit declaration of function 'kfree'

Caused by commit d103d3b3e8512312b5254950035366d4422a479a ("percpu: don't
implicitly include slab.h from percpu.h") from the slabh tree interacting
with commit 88643169de358b8e5af101151d913ad80e4c64df ("Input: add PCF8574
I2C keypad input device driver") from the input tree.

I applied the following merge fixup patch which should be applied to the
input tree (see Documentation/SubmitChecklist Rule #1 :-)).
