extcon: qcom-spmi-misc: Sync the extcon state on interrupt
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") Signed-off-by: Stephen Boyd <stephen.boyd@linaro.org> Signed-off-by: Chanwoo Choi <cw00.choi@samsung.com>
