[PATCH 3/5] staging: comedi: comedi_bond: remove private printk macros

H Hartley Sweeten hartleys at visionengravers.com
Mon Aug 20 19:53:20 UTC 2012


Remove the macros LOG_MSG, DEBUG, WARNING, and ERROR. Convert
the printk's into dev_printk format.

The DEBUG macro is not being used in the file so the module
parameter 'debug' can also be removed.
