Actually, it is not possible to initialize the name outside of the framework
because commit 20f7b53dfc24 ("extcon: Move struct extcon_cable from header file to core")
moved the 'struct extcon_dev' into drivers/extcon/extcon.c in order to prevent
the direct accessing of struct extcon_dev.

Instead of this patch, need to change the description of struct extcon_dev.
