drm/amd/display: Fix memory leak in dcn21_clock_source_create

[PATCH] drm/amd/display: Fix memory leak in dcn21_clock_source_create

Posted by Miaoqian Lin 4 years ago

When dcn20_clk_src_construct() fails, we need to release clk_src.

Fixes: 6f4e6361c3ff ("drm/amd/display: Add Renoir resource (v2)")
