USB: add SPDX identifiers to all remaining files in drivers/usb/ It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the drivers/usb/ and include/linux/usb* files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This work is based on a script and data from Thomas Gleixner, Philippe Ombredanne, and Kate Stewart.

usb: dwc3: fix incorrect kernel-doc comment syntax in files 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.

usb: dwc3: add tracepoints to aid debugging When we're debugging hard-to-reproduce and time-sensitive use cases, printk() poses too much overhead. That's when the kernel's tracing infrastructure comes into play. This patch implements a few initial tracepoints for the dwc3 driver. More traces can be added as necessary in order to ease the task of debugging dwc3. Reviewed-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

usb: dwc3: Replace HTTP links with HTTPS ones Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.
