The pin shutup callback seems working well on some devices while it
does harm on some other devices; e.g. Lenovo laptops show often the
noises at (runtime) PM with the pin shutup enabled.

Currently, the only way to disable the pin shutup is to hard-code
  spec->shutup = alc_no_shutup;
in the fixup, and this makes the debugging harder for normal users.
For allowing users to test the similar effect without recompiling the
kernel, this patch adds a new hint string "shutup".  It's a boolean
value, and by passing false to this, user can turn off the pin shutup
call.

For example, to turn off the shutup on Lenovo P50, create a "firmware
patch" file (e.g. /lib/firmware/alsa/lenovo-p50) containing the
following lines:

  [codec]
  0x10ec0298 0x17aa222e 0

  [hint]
  shutup = no

and pass the file via patch option of snd-hda-intel module
(e.g. patch=alsa/lenovo-p50).

The vmalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vmalloc(a * b)

with:
        vmalloc(array_size(a, b))

as well as handling cases of:

        vmalloc(a * b * c)

with:

        vmalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vmalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

When 'kzalloc()' fails in 'snd_hda_attach_pcm_stream()', a new pcm instance is
created without setting its operators via 'snd_pcm_set_ops()'. Following
operations on the new pcm instance can trigger kernel null pointer dereferences
and cause kernel oops.

This bug was found with my work on building a gray-box fault-injection tool for
linux-kernel-module binaries. A kernel null pointer dereference was confirmed
from line 'substream->ops->open()' in function 'snd_pcm_open_substream()' in
file 'sound/core/pcm_native.c'.

This patch fixes the bug by calling 'snd_device_free()' in the error handling
path of 'kzalloc()', which removes the new pcm instance from the snd card before
returns with an error code.

Added a new helper file for these fixups due to requiring a huge number

setting pin 0x17 for the top speakers and the correct input source
of 0x17 for volume control

[ Note: this is a revised work based on Tom's fixup patch with the
  replacement of the full COEF tables provided by Realtek.
  Also, the fixup function has a proper HDA_FIXUP_ACT_* handling now.

Before commit 3b5b899c ("ALSA: hda: Make use of core codec functions
to sync power state"), hda_set_power_state() returned the response to
the Get Power State verb, a 32-bit unsigned integer whose expected value
is 0x233 after transitioning a codec to D3, and 0x0 after transitioning
it to D0.

The response value is significant because hda_codec_runtime_suspend()
does not clear the codec's bit in the codec_powered bitmask unless the
AC_PWRST_CLK_STOP_OK bit (0x200) is set in the response value.  That in
turn prevents the HDA controller from runtime suspending because
azx_runtime_idle() checks that the codec_powered bitmask is zero.

Since commit 3b5b899c, hda_set_power_state() only returns 0x0 or
0x1, thereby breaking runtime PM for any HDA controller.  That's because
an inline function introduced by the commit returns a bool instead of a
32-bit unsigned int.  The change was likely erroneous and resulted from
copying and pasting snd_hda_check_power_state(), which is immediately
preceding the newly introduced inline function.  Fix it.

 Use ARRAY_SIZE instead of dividing sizeof array with sizeof an element

Semantic patch information:
 This makes an effort to find cases where ARRAY_SIZE can be used such as
 where there is a division of sizeof the array by the sizeof its first
 element or by any indexed element or the element type. It replaces the
 division of the two sizeofs by ARRAY_SIZE.
