From: H Hartley Sweeten Date: Thu, 17 Jul 2014 18:57:33 +0000 (-0700) Subject: staging: comedi: ni_mio_common: remove use of comedi_error() X-Git-Tag: v3.17-rc1~123^2~571 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=5ac1d82bb41942245f6605771a7defb8e931e317;p=karo-tx-linux.git staging: comedi: ni_mio_common: remove use of comedi_error() 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.
