1.

[linux-3.16-rc5/drivers/hsi/controllers/omap_ssi.c:357]: (style) Checking if
unsigned variable 'gdd_irq' is less than zero.

Source code is

    omap_ssi->gdd_irq = platform_get_irq_byname(pd, "gdd_mpu");
    if (omap_ssi->gdd_irq < 0) {

if unsigned variable 'irq' is less than zero.

Source code is

    omap_port->irq = platform_get_irq(pd, 0);
    if (omap_port->irq < 0) {
