From 77d2f7c24725e3caa82492dd3d1cbd466b8a0abf Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Wed, 5 Sep 2012 18:38:11 -0700 Subject: [PATCH] staging: comedi: das800: 'dev->subdevices + 0' is already known There is no need to calculate the subdevice for the call to das800_cancel. The variable 's' in this function is set to the 'dev->read_subdev' which is the same as 'dev->subdevices + 0'.
