This is redundant - you have this info in of_is31fl319x_leds_match, and you can obtain it with of_match_device(). Please compare drivers/leds/leds-is31fl32xx.c.
we have tried like is31fl32xx.c but it does not automatically load the driver if compiled as module (like all other I2C clients do). Reason seems to be that there is no i2c information in modalias database any more.
So perhaps the i31fl32 approach is also incomplete. Has it been tested with loadable modules?
Having the issue clarified, please proceed accordingly in case of your driver.
