net: mvmdio: Check for a valid interrupt instead of an error
The following commit: commit 9ec36caf Author: Rob Herring <robh@kernel.org> Date: Wed Apr 23 17:57:41 2014 -0500 of/irq: do irq resolution in platform_get_irq changed platform_get_irq() which now returns EINVAL and EPROBE_DEFER, in addition to ENXIO. If there's no interrupt for mvmdio, platform_get_irq() returns EINVAL, but we currently check only for ENXIO. Fix this by looking for a positive integer, which is the proper way of validating a virtual interrupt number. While at it, add a proper handling for the deferral probe case.
