Subject: drm/amd/display: Fix memory leak in dcn21_clock_source_create
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=815b847af99d8b78131174fa1c32da0195c70e4c;p=linux.git

drm/amd/display: Fix memory leak in dcn21_clock_source_create

[ Upstream commit 65e54987508b6f0771f56bdfa3ee1926d52785ae ]

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