From: H Hartley Sweeten Date: Fri, 8 Apr 2016 19:41:36 +0000 (-0700) Subject: staging: comedi: das1800: remove 'common' boardinfo member X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7a9254962bf3b636a3c04da69e94bc00da7d5935;p=linux-beck.git staging: comedi: das1800: remove 'common' boardinfo member The "hc" type boards do not support common mode analog inputs all the other board types do. Remove the unnecessary member from the boardinfo and use the 'id' member to determine if the SDF_COMMON flag should be set for the subdevice.
