[PATCH v2 00/10] Fix deferred probing in the USB host/gadget drivers

[Sergey Shtylyov]

Here are 10 patches against the 'usb-linus' branch of Greg KH's 'usb.git'
repo. The affected host/gadget drivers call platform_get_irq() but override
its result in case of error which prevents the deferred probing from working.
These patches now logically depend on the previously posted patch:

[PATCH v2 01/10] usb: gadget: udc: bcm63xx: fix deferred probing

[Sergey Shtylyov]

The driver overrides the error codes returned by platform_get_irq() to
-ENXIO for some strange reason, so if it returns -EPROBE_DEFER, the driver
will fail the probe permanently instead of the deferred probing. Switch to
propagating the error codes upstream.

[PATCH v2 02/10] usb: gadget: udc: gr: fix deferred probing

The driver overrides the error codes and IRQ0 returned by platform_get_irq()
to -ENODEV, so if it returns -EPROBE_DEFER, the driver will fail the probe
permanently instead of the deferred probing. Switch to propagating the error
codes upstream. IRQ0 is no longer returned by platform_get_irq(), so we now
can safely ignore it...

I don't see how this Fixes commit is related to OHCI OMAP?
