CVE-2025-40127

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

hwrng: ks-sa - fix division by zero in ks_sa_rng_init

Fix division by zero in ks_sa_rng_init caused by missing clock pointer initialization. The clk_get_rate() call is performed on an uninitialized clk pointer, resulting in division by zero when calculating delay values.

Add clock initialization code before using the clock.
