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.
Fixes: 7154b046d8f3 ("clk: imx: Add initial support for i.MXRT1050 clock driver")

The issue is found by static analysis and remains untested.

Looks good! The fix seems to be similar to how clk-imx8mn.c does this.
Acked-by: Jesse Taube <Mr.Bossman075@gmail.com>
A similar issue seems to also be in drivers/clk/imx/clk-imx8mm.c,clk-imx93.c,clk-imx8mp.c.
Sorry for recreating the issue :(.
Thanks,
Jesse Taube

Thanks for your review, I am glad to let you know that I am a student at a
university and we collaborate to contribute to the Linux kernel. Here we
have some similar patches for clk. Could you please take care of them?
