If anyone has any objections, please let me know. ------------------ From: Igor Velkov [ Upstream commit 5831f5fef10030c175e585d51b0e793dc6fef6ab ] pcf8563_irq() takes its dev_id as struct pcf8563, but probe still registers the interrupt with the i2c client. The handler then takes the regmap pointer from the wrong structure: the first alarm oopses, the level-low INT is never acknowledged, and the interrupt gets disabled as spurious. Only an RTC that has an interrupt (client->irq > 0) reaches this path.
