drm/amd/display: Add a dc_state NULL check in dc_state_release

...

The vulnerability of the `dc_state_create_copy()` function in the `drivers/gpu/drm/amd/display/dc/core/dc_state.c` file of the Linux kernel allows a attacker to compromise the confidentiality, integrity, and accessibility of the protected information.

The vulnerability of the dcstatecreatecopy function in the drivers/gpu/drm/amd/display/dc/core/dcstate.c file of the Linux kernel is related to the repeated release of previously released memory. Exploiting this vulnerability could allow an attacker to compromise the confidentiality, integrity, a...
