[PATCH 0/2] drm/atmel-hlcdc: fix memory bugs

Posted by Ludovic Desroches 3 months, 2 weeks ago

These two patches fix a memory leak and a use after free bugs.

The memory leak bug had been reported by several users. There were some
attempts to fix it in the past, but the resolutions proposed caused
other breakages.
