From 1ef6e0a48e3b624beb6f6206db2875ca3367459e Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Fri, 13 Nov 2015 11:11:18 -0700 Subject: [PATCH] staging: comedi: adv_pci1710: tidy up analog output subdev_flags Remove the SDF_COMMON flag, the analog reference is not programmable and the default aref (AREF_GROUND -> SDF_GROUND) provides adequate information about the reference.
