Subject: [PATCH 3.16 018/305] staging: comedi: quatech_daqp_cs: fix no-op
 loop daqp_ao_insn_write()

3.16.63-rc1 review patch.  If anyone has any objections, please let me know.

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 1376b0a2160319125c3a2822e8c09bd283cd8141 upstream.

There is a '>' vs '<' typo so this loop is a no-op.
