For the header files in include/linux/usb, add missing multiple inclusion protection and standardize what's already there. The apparent standards: * macro name of __LINUX_USB_headerfile_H * inclusion protection placed after leading comment block * macro name added as a comment on the final #endif * any obvious trivial whitespace cleanup associated with the above Signed-off-by: Robert P.
