Subject: linux-next: build failure after merge of the slabh tree

Hi Tejun,

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

sound/usb/pcm.c: In function 'snd_usb_pcm_check_knot':
sound/usb/pcm.c:751: error: implicit declaration of function 'kmalloc'
sound/usb/pcm.c:751: warning: assignment makes pointer from integer without a cast

Caused by commit d103d3b3e8512312b5254950035366d4422a479a ("percpu: don't
implicitly include slab.h from percpu.h") from the slabh tree interacting
with commit e5779998bf8b70e48a6cc208c8b61b33bd6117ea ("ALSA: usb-audio:
refactor code") from the sound tree.

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

Subject: [PATCH] sound: usb pcm: use of kmalloc requires the include of slab.h
