Description

In the Linux kernel, the following vulnerability has been resolved: clk: qcom: videocc-sm8350: use HW_CTRL_TRIGGER for vcodec GDSCs A recent change in the venus driver results in a stuck clock on the Lenovo ThinkPad X13s, for example, when streaming video in firefox: video_cc_mvs0_clk status stuck at 'off' WARNING: CPU: 6 PID: 2885 at drivers/clk/qcom/clk-branch.c:87 clk_branch_wait+0x144/0x15c ...
