CVE-2026-90147: Undefined Security Weakness

In the Linux kernel, the following vulnerability has been resolved:

clk: devres: fix cleanup in devm_clk_get_optional_enabled_with_rate()

devm_clk_get_optional_enabled_with_rate() registers its cleanup action before setting the clock rate. If setting the rate fails, it attempts to disable and unprepare a clock that was never enabled. This issue was spotted while reviewing "rust: clk: add devres-managed clks" [1].

Register the cleanup action only after successfully preparing and enabling the clock.
