Does not sound better to me. It's "Quirk's information", vs
"information about quirks". I prefer the first one. In term of C
namespace the orignal is also better. So the name space is UVC_QUIRK,
and the detail is INFO.
If we where to apply your logic, you'd rename driver_info, into
info_driver, because it's information about the driver.
