CVE-2023-53704

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> clk: imx: clk-imx8mp: improve error handling in imx8mp_clocks_probe()<br /> <br /> Replace of_iomap() and kzalloc() with devm_of_iomap() and devm_kzalloc()<br /> which can automatically release the related memory when the device<br /> or driver is removed or unloaded to avoid potential memory leak.<br /> <br /> In this case, iounmap(anatop_base) in line 427,433 are removed<br /> as manual release is not required.<br /> <br /> Besides, referring to clk-imx8mq.c, check the return code of<br /> of_clk_add_hw_provider, if it returns negtive, print error info<br /> and unregister hws, which makes the program more robust.
