It seems fairly implausible anyone will use this ancient device
with any other firmware, but as conversion is trivial and provides
one less place for people to copy of specific handling from
i tried applying it.
However it doesn't build...
drivers/iio/adc/twl4030-madc.c:754:24: error: ‘np’ undeclared (first use in this function); did you mean ‘up’?
754 | if (!pdata && !np) {
| ^~
| up
I guess !dev_fwnode(dev) instead?
