[PATCH] extcon: Ensure dynamically allocated sysfs attributes are initialised

[Mark Brown <broonie@opensource.wolfsonmicro.com>]

The operation of lockdep requires that all dynamically allocated sysfs
nodes are initialised using sysfs_attr_init() otherwise lots of warnings
are generated. Ensure that all the dynamically allocated attributes that
extcon generates have this done.
