Subject: staging: comedi: cb_das16_cs: remove unused timer subdevice
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=5c416ef3f67e9f524ac3ab07c071323f66616373;p=deliverable%2Flinux.git

staging: comedi: cb_das16_cs: remove unused timer subdevice

The timer subdevice is never initialized due to the 'if (0)'. The
comedi callbacks also don't do anything and just return -EINVAL.

Remove the subdevice and associated code.
