From: H Hartley Sweeten Date: Tue, 22 May 2012 22:31:41 +0000 (-0700) Subject: staging: comedi: remove this_board macro in the acl7225b driver X-Git-Tag: next-20120724~21^2~1024 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=960ca1ae1e0676dfef699c37362dad1d4fee5397;p=karo-tx-linux.git staging: comedi: remove this_board macro in the acl7225b driver The 'this_board' macro depends on having a local variable with a magic name. The CodingStyle document suggests not doing this to avoid confusion. Remove the macro and use the comedi_board() inline helper to get the dev->board_ptr information.
