[Intel-gfx] [PATCH] drm/i915/dp: Fix incorrect test parameter for DP link layer compliance

[Lee Shawn C]

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 a "\n" (newline) in
seq_printf() then DP test applet will get proper parameters.
