Change History

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.
