What do you think about this patch?
We want to set charger-manager as module in our project for new Android devices.

You are breaking the kernel if CONFIG_CHARGER_MANAGER is disabled. Why
not simple change the #ifdef to
#if IS_ENABLED(CONFIG_CHARGER_MANAGER)
?

No, now no users in mainline have called cm_notify_event() function,
and if some charger drivers want to use the charger manager, they
should select CHARGER_MANAGER, like:
config CHARGER_SC2731
tristate "Spreadtrum SC2731 charger driver"
depends on MFD_SC27XX_PMIC || COMPILE_TEST
select CHARGER_MANAGER

Yes, this also can work, and either way is okay for me. Sebastian,
what do you prefer? Thanks.
