[PATCH v2 12/14] power: supply: bq24190_charger: Remove extcon handling

Tue Aug 15 20:05:00 UTC 2017
Now that drivers/i2c/busses/i2c-cht-wc.c uses
"input-current-limit-from-supplier" instead of "extcon-name" the last
user of the bq24190 extcon code is gone, remove it.
Signed-off-by: Hans de Goede <hdegoede at redhat.com>

Changes in v2:
-Move the comment with the example code for passing properties on i2c_client
instantion to the input-current-limit-from-supplier handling to preserve
the example code
