Subject: staging: comedi: pcl818: remove unneeded tests in ai_cmdtest
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=f7f111c214f218483a23d40a1f8e2d798b6e130a;p=deliverable%2Flinux.git

staging: comedi: pcl818: remove unneeded tests in ai_cmdtest

The step 2 tests of the start_src, scan_begin_src, and scan_end_src
triggers to make sure they are unique are not needed.  These triggers
all only have one source and it was trivially validated in step 1.
