[PATCH v2 2/2] i2c: synquacer: 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
-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...
