Description

In the Linux kernel, the following vulnerability has been resolved: usb: renesas_usbhs: Reorder clock handling and power management in probe Reorder 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: usbhs_probe(
