drm/msm/dp: Add newlines to debug printks

[PATCH] drm/msm/dp: Add newlines to debug printks

Posted by Stephen Boyd 2 years, 3 months ago

These debug printks are missing newlines, causing drm debug logs to be
hard to read. Add newlines so that the messages are on their own line.

perhaps we can move sink_request to the previous line itself with this 
patch and we can avoid the line break.

But thats a very minor comment, otherwise LGTM
