The following patch caused the boot failure of both this kernel and 3.10.47-rc1.

Subject: ALSA: hda - Adjust speaker HPF and add LED support for HP Spectre 13

From: Takashi Iwai <tiwai@...e.de>

commit 8b3dfdaf0c25a584cb31d04d2574115cf2d422ab upstream.

HP Spectre 13 has the IDT 92HD95 codec, and BIOS seems to set the
default high-pass filter in some "safer" range, which results in the
very soft tone from the built-in speakers in contrast to Windows.
Also, the mute LED control is missing, since 92HD95 codec still has no
HP-specific fixups for GPIO setups.

This patch adds these missing features: the HPF is adjusted by the
vendor-specific verb, and the LED is set up from a DMI string (but
with the default polarity = 0 assumption due to the incomplete BIOS on
the given machine).

This patch uses codec_dbg(), however, this macro is intrdocuded by the
following patch and it's not applied to these stable-tree yet.

    ALSA: hda - Replace with standard printk

    Use dev_err() and co for messages from HD-audio controller and codec
    drivers.  The codec drivers are mostly bound with codec objects, so
    some helper macros, codec_err(), codec_info(), etc, are provided.
    They merely wrap the corresponding dev_xxx().

    There are a few places still calling snd_printk() and its variants
    as they are called without the codec or device context.

Unfortunately I failed to apply this patch to 3.14.11-rc1 with the following
error log.

===============================================================================
$ git apply ~/src/test-linux-stable/extra_patch.txt 
error: patch failed: sound/pci/hda/hda_intel.c:897
error: sound/pci/hda/hda_intel.c: patch does not apply
error: sound/pci/hda/hda_sysfs.c: No such file or directory
===============================================================================

I'm not sure whether we should drop this patch or should apply extra patches
to remove this build failure. Any idea?

Thanks,
Satoru
