Now snd_ac97_bus() takes the const ops pointer, so we can define the
snd_ac97_bus_ops locally as const as well for further optimization.There should be no functional changes by this patch.

snd_trident_ioctl() does nothing but calling the default handler.

snd_pcm_sgbuf_ops_page is no longer needed to be set explicitly to PCM
page ops since the recent change in the PCM core (*). Leaving it NULL
should work as long as the preallocation has been done properly.This patch drops the redundant lines.

The meddlesome gcc warns about the possible shortname string in
trident driver code:
sound/pci/trident/trident.c: In function ‘snd_trident_probe’:
sound/pci/trident/trident.c:126:2: warning: ‘strcat’ accessing 17 or more bytes at offsets 36 and 20 may overlap 1 byte at offset 36 [-Wrestrict]
strcat(card->shortname, card->driver);It happens since gcc calculates the possible string size from
card->driver, but this can't be true since we did set the string just
before that, and they are much shorter.For shutting it up, use the exactly same string set to card->driver
for strcat() to card->shortname, too.Signed-off-by: Takashi Iwai

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:
