From 8c41e9f41bd5543cb14e617b9626d2640ce3240f Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 9 Dec 2013 15:31:06 -0700 Subject: [PATCH] staging: comedi: pcmmio: remove 'asic' member from subdevice private data This member of the subdevice private data is always initialized to '0' by the only subdevice that uses it. Since we only have one asic on the board it's really not needed. Just remove it.
