That's an unrelated an incorrect style change. You need a blank line
after declaration.

[PATCH 0/4] drm: add support for retrieving EDID via ACPI _DDC
Some notebook systems provide the EDID for the internal panel via the
_DDC method in ACPI, instead of or in addition to providing the EDID via
DDC on LVDS/eDP. Add a DRM helper to search for an ACP _DDC method under
the ACPI namespace for each VGA/3D controller, and return the first EDID
successfully retrieved via _DDC. Update the i915, nouveau, and radeon
DRM-KMS drivers to fall back to
