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)

Hi Max,

The fsl_ssi driver is buggy here. irq_of_parse_and_map() returns 0 on error, 
not NO_IRQ. Also, see http://lwn.net/Articles/470820/.

Ok, I'll post another one with NO_IRQ defined as 0 in order to allow building
allmodconfig.
