[PATCH] power: supply: max8997_charger: make EXTCON dependency unconditional

[Arnd Bergmann]

From: Arnd Bergmann <arnd@xxxxxxxx>

Some of the extcon interfaces have a fallback implementation that can
be used when EXTCON is disabled, but some others do not, causing a
build failure:

drivers/power/supply/max8997_charger.c:261:9: error: implicit declaration of function 'devm_extcon_register_notifier_all' [-Werror,-Wimplicit-function-declaration]
                ret = devm_extcon_register_notifier_all(&pdev->dev, charger->edev,
                      ^
drivers/power/supply/max8997_charger.c:261:9: note: did you mean 'devm_extcon_register_notifier'?
include/linux/extcon.h:263:19: note: 'devm_extcon_register_notifier' declared here
static inline int devm_extcon_register_notifier(struct device *dev,

I assume there is no reason to actually build this driver without extcon
support, so a hard dependency is the easiest fix. Alternatively the
header file could be extended to provide additional inline stubs.
