w1: omap-hdq: fix error return code in omap_hdq_probe()
platform_get_irq() returns an error code, but the omap_hdq driver ignores it and always returns -ENXIO. This is not correct, and prevents -EPROBE_DEFER from being propagated properly. Notice that platform_get_irq() no longer returns 0 on error. Print error message and propagate the return value of platform_get_irq on failure. Signed-off-by: Gustavo A. R.
