Subject: [ALSA/hda] kernel BUG at drivers/base/driver.c:152!
Greetings,
0day kernel testing robot got the below dmesg and the first bad commit is
git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound.git topic/hda-regmap
commit 3103d80b8a89f1797e87d7265f9b389a0db4ccd8
Author: Takashi Iwai <tiwai@...e.de>

ALSA: hda - Make snd_hda_bus_type public
Define the common hd-audio driver and device types to bind over
snd_hda_bus_type publicly. This allows to implement other type of
device and driver code over hd-audio bus.
Now both struct hda_codec and struct hda_codec_driver inherit these
new struct hdac_device and struct hdac_driver, respectively.
