[PATCH v2] pata_ep93xx: fix deferred probing

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

 



The driver overrides the error codes returned by platform_get_irq() to
-ENXIO, so if it returns -EPROBE_DEFER, the driver would fail the probe
permanently instead of the deferred probing.  Propagate the error code
upstream, as it should have been done from the start...
