Hmm. I've already merged this, but my clang build shows that this looks buggy:

drivers/gpu/drm/amd/amdgpu/amdgpu_dm/amdgpu_dm_debugfs.c:3015:53:
warning: address of 'aconnector->mst_port->mst_mgr' will always
evaluate to 'true' [-Wpointer-bool-conversion]
                        if (!(aconnector->port &&
&aconnector->mst_port->mst_mgr))
                                               ~~  ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~

and yeah, checking for the address of a member of a structure benign
NULL doesn't really work.

I'm assuming the '&' is just a left-over cut-and-paste error or something.

Please fix after reviewing (I'm not going to blindly just remove the
'&' just to silence the warning, since I don't know the code).
