mlxbf_gige: return EPROBE_DEFER if PHY IRQ is not available

Browse source

[ Upstream commit e7ea5f5b18 ]

The message "Error getting PHY irq. Use polling instead"
is emitted when the mlxbf_gige driver is loaded by the
kernel before the associated gpio-mlxbf driver, and thus
the call to get the PHY IRQ fails since it is not yet
available. The driver probe() must return -EPROBE_DEFER
if acpi_dev_gpio_irq_get_by() returns the same.
