drivers/hsi/controllers/omap_ssi{,_port}.c: fix failure checks
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) {
2.
[linux-3.16-rc5/drivers/hsi/controllers/omap_ssi_port.c:1017]: (style) Checking
if unsigned variable 'irq' is less than zero.
Source code is
omap_port->irq = platform_get_irq(pd, 0);
if (omap_port->irq < 0) {
