From 06b66dc22b83fd3d9e4de42011dc5de04a226971 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Thu, 20 Nov 2014 15:07:23 -0700 Subject: [PATCH] staging: comedi: cb_pcidas: remove unnecessary check in caldac_8800_write() The 'address' passed to this function is actually the comedi channel. This value will always be less than the subdevice n_chan (which is 8). Remove the unnecessary sanity check in caldac_8800_write().
