staging: comedi: dyna_pci10xx: Set number of AO channels to 1
The "dyna_pci10xx" driver supports the Dynalog India PCI-1050. There
seems to be very little online information available about this card,
but as far as I can tell[*], it only has 1 AO (analog output) channel,
not 16 AO channels as reported in the Comedi subdevice information.
Besides, the Comedi "insn_write" handler for the AO subdevice takes no
account of channel numbers. Change the `n_chans` member of the AO
subdevice structure to 1 to reflect this.
[*] The card is no longer mentioned on the manufacturer's web-site and I
couldn't find any archived page for the site on archive.org. I found
part of a scientific paper which describes the card as having a single
channel D/A converter:
