[ Upstream commit 5c8121262484d99bffb598f39a0df445cecd8efb ]
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...
