+Patch provided by Techwolf overlay, imported to Megacoffee overlay on 19 Feb 2017
+
+This inofficial patch attempts to add compatibility with Linux kernel 4.9 (otherwise only kernels up to 4.7, maybe 4.8 will work).
+Applying this patch may void warranty but at least temporarily cancels support with Blackmagic, apply at your own risk!
+Staying with an older, officially supported kernel is recommended instead of applying this patch.
