staging: comedi: dt3000: convert driver to attach_pci

Browse source

Convert this driver to use the comedi PCI auto config mechanism
by adding an attach_pci callback.

Since this driver requires no extra configuration options, and
the attach callback is now optional, remove it.

Remove the kernel noise that is output when the attach fails
for various reasons.

Use the found 'dev->board_name' for the resource name passed to
comedi_pci_enable() and request_irq().

Pass on the error returned from request_irq() instead of returning
-EINVAL on error.

Since this driver no longer walks the pci bus to find the pci_dev,
remove the pci_dev_put() in the detach.
