Condition 'i<count' is always false

[woko1754]

Hi, I have a piece of code, where one line is criticized with the above message, and I can't find the reason. Can this be a bug ?

while (tx_len > 0) {
    while (bcm2835_peri_read(stat) & BCM2835_AUX_SPI_STAT_TX_FULL)
        ;

    uint32_t count = MIN(tx_len, 3);
    uint32_t data = 0;

      for (i = 0; i < count; ++i) {             /* <== related line */
        byte = (tx != NULL) ? (uint8_t)*tx++ : (uint8_t)0;
        data |= (uint8_t)(byte << (8 * (2 - i)));
    }

    data |= (count * 8) << 24;
    tx_len -= count;

    if (tx_len != 0)
        bcm2835_peri_write(txhold, data);
    else
        bcm2835_peri_write(io, data);

    while (bcm2835_peri_read(stat) & BCM2835_AUX_SPI_STAT_BUSY)
        ;

    (void)bcm2835_peri_read(io);
}

I can't reproduce this with the code you posted.
