Affected: Alpaquita:23: linux-lts, Alpaquita:stream: linux-lts

In the Linux kernel, the following vulnerability has been resolved:

clk: imx: clk-imxrt1050: fix memory leak in imxrt1050_clocks_probe

Use devm_of_iomap() instead of of_iomap() to automatically handle the unused ioremap region. If any error occurs, regions allocated by kzalloc() will leak, but using devm_kzalloc() instead will automatically free the memory using devm_kfree().

Also, fix error handling of hws by adding unregister_hws label, which unregisters remaining hws when iomap failed.
