Hi Lee,
Right now, as you suggested I rewrote code like below
For of_device_id,
. data = (void *)MAX77540,
.data = (void *)MAX77541,
For i2c_device_id,
.data = MAX77540,
.data = MAX77541
I also rewrote other part as chip_info is excluded. I want to be sure before
sending new patch.
Does it seem correct?
