mraa_uart_write(): off by one while writing arrays

[Sahaj Sarup]

hi,
I have a uint8_t data[256] array.
If I read into it using mraa_uart_read(uart, data, 256); it works fine but if I write from it using mraa_uart_write(uart, data, 256); it seems to write from n-1, ie the first element being -1 and the last being 254.
however if i write from it in a loop like so, it works fine:

for(int i = 0; i < 256; i++)
    {
        mraa_uart_write(uart, &recv_data[i], 1);
    }

sorry for the noise, this behavior doesn't seem consistent so i'll lest it a bit more.
