Subject: drm/i915: Refactor debugfs display info code
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Git-commit: 647542337786fc87cc1e8c48ee2c3cec92c2bc80
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322

Pull the crtc dumping stuff into a nice function so the
loop over the crtcs doesn't look like crap.
