Miaoqian Lin e937440f7f spi: meson-spicc: add IRQ check in meson_spicc_probe ...

This check misses checking for  platform_get_irq()'s call and may passes
the negative error codes to devm_request_irq(), which takes unsigned IRQ #,
causing it to fail with -EINVAL, overriding an original error code.
Stop calling devm_request_irq() with invalid IRQ #s.
