Harald Welte e42492971e pio_it.c: Permit repeated calls to PIO_ConfigureIt() ... The original code assumes that calls to PIO_ConfigureIt() are only made once e.g. during board start-up. Hoewever, we call those at USB SetConfiguration time, when we know which particular hardware function we are supposed to perform. This means that after the host has issued SetConfiguration more than a given number of times, the code will assert() due to overflow of the static array. Let's check if we already have allocated an array slot for a given pin and reuse that allocated array bucket rather than allocating new ones for the same pin.
