NO_IRQ may be defined as '(unsigned int) -1' in some architectures
(arm, sh ...), and either may not be defined in some architectures
which can enable SND_SOC_FSL_SSI (e.g. allmodconfig for arc).
When irq_of_parse_and_map() fails, it will always return 0, so need let
checking none-zero instead of checking NO_IRQ, or will cause compiling
issue or run time bug in some architectures.

Oh, sorry, the subject and comment are incorrect, need use "zero"
instead of "none-zero".
I will send patch v2 for it.
