The opening comment mark '/**' is used for highlighting the beginning of kernel-doc comments. There are certain files in drivers/usb/dwc3, which follow this syntax, but the content inside does not comply with kernel-doc. Such lines were probably not meant for kernel-doc parsing, but are parsed due to the presence of kernel-doc like comment syntax(i.e, '/**'), which causes unexpected warnings from kernel-doc. E.g., presence of kernel-doc like comment in drivers/usb/dwc3/io.h at header causes this warnings by kernel-doc: "warning: expecting prototype for h(). Prototype was for __DRIVERS_USB_DWC3_IO_H() instead" Similarly for other files too. Provide a simple fix by replacing such occurrences with general comment format, i.e. '/*', to prevent kernel-doc from parsing it.
