Summary
drm/amd/display: Fix out-of-bound accesses
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Fix out-of-bound accesses

[WHAT & HOW] hpostreamtolinkencodermapping has size MAXHPODP2ENCODERS(=4), but location can have size up to 6. As a result, it is necessary to check location against MAXHPODP2_ENCODERS.

Similiarly, dispcfgstream_location can be used as an array index which should be 0..5, so the ASSERT's conditions should be less without equal.
