[PATCH v2 05/10] usb: host: ehci-orion: fix deferred probing

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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...

Fixes: e96ffe2f9deb ("USB: add Marvell Orion USB host support")

Changes in version 2:
- removed the check for IRQ0, updated the patch description accordingly.
