Arvind Yadav 5d3806eea2 ALSA: nm256: constify snd_ac97_res_table
snd_ac97_res_table are not supposed to change at runtime. All functions
working with snd_ac97_res_table provided by <sound/ac97_codec.h> work with
const snd_ac97_res_table. So mark the non-const structs as const.

Takashi Iwai 21de567366 ALSA: nm256: Convert to new PCM copy ops
Replace the copy and the silence ops with the new ops.
The conversion is straightforward with standard helper functions, and
now we can drop the bytes <-> frames conversions in callbacks.

Julia Lawall 6769e988b0 ALSA: constify snd_pcm_ops structures
Check for snd_pcm_ops structures that are only stored in the ops field of a
snd_soc_platform_driver structure or passed as the third argument to
snd_pcm_set_ops.  The corresponding field or parameter is declared const,
so snd_pcm_ops structures that have this property can be declared as const
also.

Takashi Iwai fc9b6061cf ALSA: nm256: Simplify PM callbacks
This is a similar cleanup like the commit [3db084fd0a: ALSA: fm801:
PCI core handles power state for us].

Since pci_set_power_state(), pci_save_state() and pci_restore_state()
are already done in the PCI core side, so we don't need to it doubly.

Also, pci_enable_device(), pci_disable_device() and pci_set_master()
calls in PM callbacks are superfluous nowadays, too, so get rid of
them as well.

Takashi Iwai 20a24225d8 ALSA: PCI: Remove superfluous pci_set_drvdata(pci, NULL) at remove
As drvdata is cleared to NULL at probe failure or at removal by the
driver core, we don't have to call pci_set_drvdata(pci, NULL) any
longer in each driver.

The only remaining pci_set_drvdata(NULL) is in azx_firmware_cb() in
hda_intel.c.  Since this function itself releases the card instance,
we need to clear drvdata here as well, so that it won't be released
doubly in the remove callback.

Takashi Iwai 86b2723725 ALSA: Make snd_printd() and snd_printdd() inline
Because currently snd_printd() and snd_printdd() macros are expanded
to empty when CONFIG_SND_DEBUG=n, a compile warning like below
appears sometimes, and we had to covert it by ugly ifdefs:
  sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’:
  sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable]

For "fixing" these issues better, this patch replaces snd_printd() and
snd_printdd() definitions with empty inline functions instead of
macros.  This should have the same effect but shut up warnings like
above.

But since we had already put ifdefs, changing to inline functions
would trigger compile errors.  So, such ifdefs is removed in this
patch.

In addition, snd_pci_quirk name field is defined only when
CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in
snd_printdd() argument triggers the build errors, too.  For avoiding
these errors, introduce a new macro snd_pci_quirk_name() that is
defined no matter how the debug option is set.

it'll simply give a warning, but it'll break next kernel version.

Takashi Iwai 934c2b6d0c ALSA: use KBUILD_MODNAME for request_irq argument in sound/pci/*
The name argument of request_irq() appears in /proc/interrupts, and
it's quite ugly when the name entry contains a space or special letters.
In general, it's simpler and more readable when the module name appears
there, so let's replace all entries with KBUILD_MODNAME.

Takashi Iwai 3733e424c4 ALSA: Use KBUILD_MODNAME for pci_driver.name entries
The convention for pci_driver.name entry in kernel drivers seem to be
the module name or equivalent ones.  But, so far, almost all PCI sound
drivers use more verbose name like "ABC Xyz (12)", and these are fairly
confusing when appearing as a file name.

This patch converts the all pci_driver.name entries in sound/pci/* to
use KBUILD_MODNAME for more unified appearance.
