Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] Unconditional assignment of conditionally compiled `.complete` and `.prepare` PM callbacks in `dwc3_rockchip_dev_pm_ops` causes a build failure when `CONFIG_PM_SLEEP` is disabled.

usb: dwc3: rockchip: introduce glue driver

Introduce Rockchip specific glue code for the Synopsys DWC3 USB driver.
For now this handles things identical to the default glue.

[Severity: Low]
Will this cause a build failure when CONFIG_PM_SLEEP is disabled?

The functions dwc3_rockchip_complete() and dwc3_rockchip_prepare() are
defined inside an #ifdef CONFIG_PM_SLEEP block, but they are referenced
unconditionally here in dwc3_rockchip_dev_pm_ops.

This would leave them undeclared if sleep support is not configured.
