[PATCH] power: supply: ab8500: Fix memory leak in ab8500_chargalg_sysfs_init

[Miaoqian Lin]

kobject_init_and_add() takes reference even when it fails.
According to the doc of kobject_init_and_add()

   If this function returns an error, kobject_put() must be called to
   properly clean up the memory associated with the object.

Fix this issue by adding kobject_put().
