CONFIG_COMEDI_PCI_DRIVERS to make sure the 8255 driver

the 8255 support.

staging: comedi: change device used in dev_...() calls

A previous set of patches by Ravishankar Karkala Mallikarjunayya
replaced a load of printk() calls with dev_info(), dev_err(), etc.
Unfortunately, these used the 'struct device *hw_dev' member of 'struct
comedi_device') as the first parameter of these dev_...() calls, but
that pointer is usually NULL, so the kernel log messages come out a bit
wrong (they contain the phrase "(NULL device *)").

Use the 'struct device *class_dev' member of 'struct comedi_device'
instead for these dev_...() calls.  It will be non-NULL and somewhat
meaningful to users.  It's also consistent with those comedi drivers
that already use the class_dev member in their dev_...() calls.

Some of the messages included the format "comedi%d" with the minor
device number used for the "%d".  This is now redundant as it will be
the same as the dev_name() part of the kernel log message produced by
the dev_...() calls.

iio: buffer: Fix NULL pointer deref caused by empty scan mask

iio_scan_mask_match() returns NULL if the passed in scan mask is empty. This
will happen if no channel has been selected and buffer is enabled.
iio_sw_buffer_preenable() will assign NULL to indio_dev->active_scan_mask in
this case. As a result iio_update_demux() will cause a NULL pointer deref,
because it expects active_scan_mask to be non-NULL.

Since it does not make much sense to start data capture if there is no data to
capture this patch updates the code to fail gracefully in iio_scan_mask_match()
instead of crashing the kernel.
