# \[PATCH v2\] pata\_ep93xx: fix deferred probing - From: Sergey Shtylyov \ - Date: 2021-03-20 20:33:18 - List: linux-ide - Page: https://ratatoskr.run/linux-ide/2021/03/16727676 - Thread: https://ratatoskr.run/linux-ide/2021/03/16727676/t.md ```text 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...
