This fixes the following allmodconfig build error:

sound/soc/fsl/fsl_ssi.c: In function 'fsl_ssi_probe':
sound/soc/fsl/fsl_ssi.c:939:26: error: 'NO_IRQ' undeclared (first use in this function)

Previous definitions (-1) were correct when used as a hardware IRQ number,
but are incorrect as a mapped IRQ number.

Shouldn't sound/soc/fsl/fsl_ssi.c be changed instead:

-if (ssi_private->irq == NO_IRQ) {
+if (!ssi_private->irq) {

Cfr. the thread https://lkml.org/lkml/2013/7/25/642

Gr{oetje,eeting}s,

I agree, this needs to be fixed too.

I saw that thread and I don't see that patch applied anywhere.

Thanks.
