From: H Hartley Sweeten Date: Tue, 29 Jul 2014 22:01:37 +0000 (-0700) Subject: staging: comedi: mite: pass comedi_device to mite_setup() X-Git-Tag: firefly_0821_release~176^2~3491^2~105 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=3bb7c3abe34349a5f3615159d80aaee25c34e2a7;p=firefly-linux-kernel-4.4.55.git staging: comedi: mite: pass comedi_device to mite_setup() For aesthetics, pass the comedi_device to mite_setup() and mite_setup2() so that the dev->class_dev can be used in the dev_{level} message to make the messages have consistancy with the other comedi drivers. Remove the extra dev_warn() noise in the drivers when mite_setup() fails. Rename the 'use_iodwbsr_1' parameter and change it to a bool.
