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

drm/amd/display: increase max link count and fix link->enc NULL pointer access

[why]
1.) dc->links[MAX_LINKS] array size smaller than actual requested.
max_connector + max_dpia + 4 virtual = 14.
increase from 12 to 14.

2.) hw_init() access null LINK_ENC for dpia non display_endpoint.
