    ALSA: pcm: add more format names · 7a28826a

    There were some new formats added in commit 15c0cee6 "ALSA: pcm:
    Define G723 3-bit and 5-bit formats".  That commit increased
    SNDRV_PCM_FORMAT_LAST as well.  My concern is that there are a couple
    places which do:
    
            for (i = 0; i < SNDRV_PCM_FORMAT_LAST; i++) {
                    if (dummy->pcm_hw.formats & (1ULL << i))
                            snd_iprintf(buffer, " %s", snd_pcm_format_name(i));
            }
    
    I haven't tested these but it looks like if "i" were equal to
    SNDRV_PCM_FORMAT_G723_24 or higher then we might read past the end of
    the array.
