Subject[PATCH 1/5] extcon: Allow extcon drivers to specify the extcon name
Date
The parent device name is not necessarily always useful, e.g.
with i2c devices it may simply be e.g.: "0-0022" and it also depends
on the i2c-bus number which depends on probe ordering.

This commit allows drivers to set their own, more useful name,
avoiding the problems with some i2c-device names.
