From: H Hartley Sweeten Date: Wed, 30 Jan 2013 23:45:09 +0000 (-0700) Subject: staging: comedi: ni_daq_dio24: remove thisboard macro X-Git-Tag: firefly_0821_release~3680^2~1080^2~179 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=fb89942cb3bff23a3bf8b799ae6f255a137eb775;p=firefly-linux-kernel-4.4.55.git staging: comedi: ni_daq_dio24: remove thisboard macro The 'thisboard' macro relies on a local variable having a specific name and yields a pointer derived from that local variable. Replace the macro with a local variable and use the comedi_board() helper to get the pointer.
