From fdb7c3ece29fc4d73e5994af6a58b4e3d55d105c Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 23 Feb 2015 14:57:58 -0700 Subject: [PATCH] staging: comedi: amplc_dio200_common: remove 'which' from struct dio200_subdev_8254 This member is only used in the "set gate" and "set clock" helper functions. Remove it and calculate the value when needed.
