At quick glance, this looks good, but one thing overall stood out:

When using dev_*() functions, you do not need a "driver prefix" here
like NCT_DRVNAME as it already is in the string that is sent to the
kernel log.  So that all can be removed from all of these.

Also:

The __func__ is already in the dev_dbg() output, so no need to repeat it
again please.

This should be done for all of the calls like this in the driver.

When drivers are working properly, they are quiet, so no need for this
line at all.
