      "summary": "In the Linux kernel, the following vulnerability has been resolved:\n\nrtc: pcf8563: fix clock provider leak on unbind\n\npcf8563_clkout_register_clk() registers the CLKOUT clock provider with\nof_clk_add_provider(), but nothing ever unwinds it: there is no\nof_clk_del_provider() call and the driver has no remove callback. Each\nof_clk_add_provider() allocates a struct of_clk_provider, takes a\nreference on the OF node and adds an entry to the global of_clk_providers\nlist, none of which is released when the device is unbound. Every\nbind/unbind (or module reload) therefore leaks a provider structure and\nan of_node reference.\n\nThe clock itself is already device-managed (devm_clk_register()); only\nthe provider registration was not. Use devm_of_clk_add_hw_provider() so\nthe provider is removed automatically on unbind. Tie it to the parent\ni2c device, whose OF node carries the #clock-cells and clock-output-names\nproperties (the RTC class device has no OF node of its own).",
