Revert "drm/ttm: fix memleak in ttm_transfered_destroy"

2021-11-06T12:59:45+00:00

This reverts commit bd99782f3ca491879e8524c89b1c0f40071903bd 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.

drm/msm: Fix null pointer dereference on pointer edp

2021-10-20T09:40:17+00:00

commit 2133c4fc8e1348dcb752f267a143fe2254613b34 upstream. The initialization of pointer dev dereferences pointer edp before edp is null checked, so there is a potential null pointer deference issue. Fix this by only dereferencing edp after edp has been null checked.
