    ALSA: Make snd_printd() and snd_printdd() inline · 86b27237

    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.
