The GPIO core provides a handy GPIO_LOOKUP() macro to populate a struct gpiod_lookup array without having to spell out attribute names (but still avoid breakage when attributes within the struct are rearranged or added). The axp288_adc.c driver uses a similar macro to populate a struct iio_map array. Make it available to others. Cc: Chen-Yu Tsai <wens@csie.org> Cc: Jacob Pan <jacob.jun.pan@linux.intel.com> Signed-off-by: Lukas Wunner <lukas@wunner.de> --- The motivation for this change is that we're using it in a module which is currently out-of-tree. I'm only converting axp288_adc.c here as it already has such a macro, and not all the other drivers which declare iio_map arrays because such trivial refactoring is not always welcome. I could convert these other drivers as well if desired. If so, please let me know if this should all be put in a single patch or split per driver. Note that I've replaced _adc_channel_label with _provider_channel, which is more apt in my opinion. Please shout if you disagree.
