PM / devfreq: tegra: fix error return code in tegra_devfreq_probe()
platform_get_irq() returns an error code, but the tegra-devfreq
driver ignores it and always returns -ENODEV. This is not correct,
and prevents -EPROBE_DEFER from being propagated properly.
Notice that platform_get_irq() no longer returns 0 on error:

Print and propagate the return value of platform_get_irq on failure.
