+
+This reverts commit c21b4002214c1c7e7b627b9b53375612f7aab6db which is
+commit 0db55f9a1bafbe3dac750ea669de9134922389b5 upstream.
+
+Seems that the older kernels can not handle this fix because, to quote
+Christian:
+       The problem is this memory leak could potentially happen with
+       5.10 as wel, just much much much less likely.
+
+       But my guess is that 5.10 is so buggy that when the leak does
+       NOT happen we double free and obviously causing a crash.
+
+So it needs to be reverted.
