[PATCH] staging: comedi: hwdrv_apci1500: use dev->class_dev in calls to dev_warn()

Wed Sep 3 23:58:49 UTC 2014


git-grep reveals that hwdrv_apci1500.c is the only file in comedi that uses
dev->hw_dev in calls to dev_{err,warn}().  The rest of the drivers pass
dev->class_dev to these macros instead.  Switch the dev_warn() calls in
this driver to use dev->class_dev as well, for consistency.

As an aside, it looks like lots of these cases are actually error
conditions that might be more appropriate use cases for dev_err().  But
they could be changed in a follow on patch, this is enough for this one.
