Subject: [PATCH] [media] cx25821, cx88, tm6000: use SNDRV_DEFAULT_ENABLE_PNP

Instead of manually initializing the bool array enable, use the
SNDRV_DEFAULT_ENABLE_PNP macro. As most drivers do.

Hi,

I don't see any good reason to use = 1 instead of = SNDRV_DEFAULT_ENABLE_PNP.
Semantically it is the same, and I don't find a purpose to explicitely set the
first element of the array separately.

The proposed patch makes these drivers consistent with the rest and more
readable. In a related note, maybe the dummy driver in sound/drivers/dummy.c
should be updated as well.

I can split this below fix into a patch per driver if that's better.

Thanks,
Luis
