Summary
In the Linux kernel, the following vulnerability has been resolved: rtc: amlogic-a4: fix double free caused by devm The clock obtained via devm_clk_get_enabled() is automatically managed by devres and will be disabled and freed on driver detach. Manually calling clk_disable_unprepare() in error path and remove function causes double free. Remove the redundant clk_disable_unprepare() calls from the probe error path and aml_rtc_remove(), allowing the devm framework to automatically manage the clock lifecycle.
