power: supply: twl4030-charger: remove nonstandard max_current sysfs attribute
Since we now support the standard 'input_current_limit' property by commit 3fb319c2cdcd ("power: supply: twl4030-charger: add writable INPUT_CURRENT_LIMIT property") we can now remove the nonstandard 'max_current' sysfs attribute. See Documentation/power/power_supply_class.txt line 125 Both are functionally equivalent. From ABI point of view it is just a rename of the property. This also removes the entry in Documentation/ABI/testing/sysfs-class-power-twl4030 Signed-off-by: H. Nikolaus Schaller <hns@goldelico.com> Signed-off-by: Sebastian Reichel <sre@kernel.org>
