+Subject: [PATCH 0337/4131] drm/amd/display: Memory was freed twice during
+ disable
+
+1. get_ss_info_from_atombios function was allocating the memory populating the provided pointer
+but them freeing the memory.
+Since the pointer was return as a valid value, we are trying to free the same memory during clock resource destruction
