irq_reg_stride in struct regmap_irq_chip is often 0, but that actually means to use the default stride of 1. The effective stride is stored in struct regmap_irq_chip_data->irq_reg_stride and will get the corrected default value. The default ->get_irq_reg() callback was using the stride from the chip definition, which is wrong; fix it to use the effective stride from the chip data instead.
