Most writes to configfs handle an optional newline, but do not require it. By using the number of bytes written as the limit for scnprintf() it is guaranteed that the final character in the buffer will be overwritten. This is expected if it is a newline but is undesirable when a string is written "as-is" (as libusbgx does, for example). Update the store function to strip an optional newline, matching the behaviour of usb_string_copy().
