CVE-2025-38635

In the Linux kernel, the following vulnerability has been resolved: clk: davinci: Add NULL check in davinci_lpsc_clk_register() devm_kasprintf() returns NULL when memory allocation fails. Currently, davinci_lpsc_clk_register() does not check for this case, which results in a NULL pointer dereference. Add NULL check after devm_kasprintf() to prevent this issue and ensuring no resources are left allocated.
