CVE-2023-53572
clk: imx: scu: use _safe list iterator to avoid a use after free
Description

In the Linux kernel, the following vulnerability has been resolved: clk: imx: scu: use _safe list iterator to avoid a use after free This loop is freeing "clk" so it needs to use list_for_each_entry_safe(). Otherwise it dereferences a freed variable to get the next item on the loop.
