Subject: [PATCH] extcon: qcom-spmi-misc: Sync the extcon state on interrupt
Date: Mon, 17 Oct 2016 17:16:02 -0700	[thread overview]
Message-ID: <20161018001602.18617-1-stephen.boyd@linaro.org> (raw)

The driver was changed after submission to use the new style APIs
like extcon_set_state(). Unfortunately, that only sets the state,
and doesn't notify any consumers that the cable state has
changed. Use extcon_set_state_sync() here instead so that we
notify cable consumers of the state change. This fixes USB
host-device role switching on the db8074 platform.

Fixes: 38085c987f52 ("extcon: Add support for qcom SPMI PMIC USB id detection hardware")
