Antonio Quartulli aa6358430a drm/amdgpu: prevent NULL pointer dereference if ATIF is not supported
commit a6dd15981c03f2cdc9a351a278f09b5479d53d2e upstream.

acpi_evaluate_object() may return AE_NOT_FOUND (failure), which
would result in dereferencing buffer.pointer (obj) while being NULL.

Although this case may be unrealistic for the current code, it is
still better to protect against possible bugs.

Bail out also when status is AE_NOT_FOUND.

This fixes 1 FORWARD_NULL issue reported by Coverity
Report: CID 1600951:  Null pointer dereferences  (FORWARD_NULL)
