This is not at all what I had in mind. First, it's incorrect (can you
see why?). Second, by "inline" I meant moving the code to be actually
in-line next to the conditional, not some place else in a separate
subroutine (even if the subroutine is declared inline).
Interesting... let me double check.
I thought it would've been better to have separate inline
subroutines for those "goto".
Also, the code for the USB_ENDPOINT_XFER_BULK case should look like the
other two.
Do you mean a 'continue' instead of the 'break'?
Oh I see, the following piece of code should be part of the
USB_ENDPOINT_XFER_BULK case:
if (usb_endpoint_dir_in(&e->desc)) {
if (!in)
in = e;
} else {
if (!out)
out = e;
}
continue;
