GHSA-4xq6-m26v-vqpr: 
In the Linux kernel, the following vulnerability has been resolved:usb: renesas_usbhs: Reorder clock handling and power management in probeReorder the initialization sequence in `usbhs_probe()` to enable runtime
PM before accessing registers, preventing potential crashes due to
uninitialized clocks.Currently, in the probe path, registers are accessed before enabling the
clocks, leading to a synchronous external abort on the RZ/V2H SoC.
The problematic call flow is as follows:Since `iowrite16()` is performed without ensuring the required clocks are
enabled, this can lead to access errors. To fix this, enable PM runtime
early in the probe function and ensure clocks are acquired before register
access, preventing crashes like the following on RZ/V2H:[13.272640] Internal error: synchronous external abort: 0000000096000010 [#1] PREEMPT SMP
