Run intel_dp_compliance would failed at video pattern related
test case sometimes. DP test applet read incorrect test type
from kernel to cause this symptom. Add "\n" (newline) in
seq_printf() then test daemon can get parameter properly.
Fixes: eb3394faeb97 ("drm/i915: Add debugfs test control
files for Displayport compliance testing")
