Title
clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe
Summary
In the Linux kernel, the following vulnerability has been resolved: clk: imx93: fix memory leak and missing unwind goto in imx93_clocks_probe In function probe(), it returns directly without unregistered hws when error occurs. Fix this by adding 'goto unregister_hws;' on line 295 and line 310. Use devm_kzalloc() instead of kzalloc() to automatically free the memory using devm_kfree() when error occurs. Replace of_iomap() with devm_of_iomap() to automatically handle the unused ioremap region and delete 'iounmap(anatop_base);' in unregister_hws.
