[PATCH 08/29] staging: comedi: ni_at_a2150: remove use of comedi_error()

[H Hartley Sweeten]

The comedi_error() function is just a wrapper around dev_err() that adds
the dev->driver->driver_name prefix to the message and a terminating
new-line character. The addition of the driver_name is just added noise
and some of the users of comedi_error() add unnecessary additional new-line
characters.

Use dev_err() directly instead of comedi_error() to avoid any confusion
and so that all the comedi generated kernel messages have the same format.
