From: Sergey Shtylyov <s.shtylyov@xxxxxx> commit 279eb8575fdaa92c314a54c0d583c65e26229107 upstream. The driver overrides the error codes returned by platform_get_irq() to -ENODEV 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 proper error codes to platform driver code upwards.
