Nothing enabled by BATTERY_BQ27XXX depends on I2C, this workaround is not
correct as it prevents BATTERY_BQ27XXX from being built-in when I2C is a

The undefined references are caused by BATTERY_BQ27XXX being built-in AND
its I2C functionality being enabled (BATTERY_BQ27XXX_I2C) while I2C is a
module. Reorganizing this driver is being discussed anyway, but in the
meantime a more correct fix would be along the lines of:
diff --git a/drivers/power/Kconfig b/drivers/power/Kconfig

Say Y here to enable support for batteries with BQ27xxx (I2C) chips.
That works too, there is just very little difference in the end here,
and it's easier to revert an patch that only introduces a regression
than to do a different hack, especially if it's going to be reworked
Do you want to submit the above as a fixup to your other patch or
should we just do the revert? It would be good to get one of the two
I can just submit this fix, it would probably be better for the short term
until the rework is done.
