So far we've ignored the errors at creating proc files in many places.
But they should be rather treated seriously.

Also, by assuring the error handling, we can get rid of superfluous
snd_info_free_entry() calls as they will be removed by the parent in
the caller side.

This patch fixes the missing error checks and reduces the superfluous
free calls.

Since each proc entry is freed automatically by the parent, we don't
have to take care of its life cycle any longer.  This allows us to
reduce a few more lines of codes.

This patch changes the way to manage the resource release of proc
files: namely, let snd_info_free_entry() freeing the whole children.

This makes it us possible to drop the snd_device_*() management.  Then
snd_card_proc_new() becomes merely a wrapper to
snd_info_create_card_entry().

Together with this change, now you need to call snd_info_free_entry()
for a proc entry created via snd_card_proc_new(), while it was freed
via snd_device_free() beforehand.

Currently, snd_info_init() just returns an error without releasing the
previously assigned resources at error path.  The assigned proc and
info entries have to be released properly.  This patch covers it.

While we are at it, refactor the code a bit, too.

seq_file is _the_ standard interface for simple text proc files.
Though, we still need to support the binary proc files and the text
file write, and also we need to manage the device disconnection
gracefully.  Thus this patch just replaces the text file read code
with seq_file while keeping the rest intact.

snd_iprintf() helper function is now a macro to expand itself to
seq_printf() to be compatible with the existing code.  The seq_file
object is stored to the unused entry->rbuffer->buffer pointer.

When the output size is expected to be large (greater than PAGE_SIZE),
the driver should set entry->size field beforehand.  Then the given
size will be preallocated and the multiple show calls can be avoided.

Some HD-A codecs may add their own vendor 'set' verb to the regmap, thru func
snd_hdac_add_vendor_verb(). This patch sets the GET bit (bit 11)  when adding
the verb so that its peer vendor 'get' verb is actually added. This can avoid
I/O error when writing the 'set' verb thru remap, since HD-A regmap internally
looks up a writable vendor verb with GET bit set at first.

Although some races in runtime PM refcount was fixed by the commit
[664c7155: ALSA: hda - Work around races of power up/down with
runtime PM], there is still a race in the following case:

CPU0:                   CPU1 :
runtime suspend:
  codec->in_pm = 1
                        snd_hdac_power_up_pm():
                          pm_runtime_get_sync() skipped
suspend finished:
  codec->in_pm = 0
                        snd_hdac_power_down_pm():
                          pm_runtime_put_*() is called!

For avoiding this situation, increment in_pm flag atomically when it's
non-zero, and decrement accordingly, to ensure that in_pm is set
consistently for the whole concurrent operations.

Also, since atomic_inc_not_zero() and atomic_dec_if_positive() are
lengthy inline functions, move snd_hdac_power_up_pm() and _down_pm()
to sound/hda/hdac_device.c as no inline functions.

An element instance can have several elements with the same feature.
Some userspace applications can add such an element instance by add
operation with the number of elements. Then, the element instance
gets a memory object to keep states of these elements.

But the element instance has just one memory object for the elements.
This causes the same result to each read/write operations to the
different elements.

This commit fixes this bug by allocating enough memory objects to the
element instance for each of elements.

The r-car sound driver only works when CONFIG_OF is set, and
after a recent change has a compile-time dependency as well:

sound/built-in.o: In function `rsnd_dma_request_channel':
:(.text+0x9fb84): undefined reference to `of_dma_request_slave_channel'

This could be fixed either by adding a static inline wrapper
for the function, or by adding a Kconfig dependency. This
implements the second approach, which seems appropriate
because the driver in fact has a hard dependency.
