From 2925d366f450dc1db0ac88f2509a0eec0fef4226 Mon Sep 17 00:00:00 2001 From: Stephen Boyd Date: Mon, 17 Oct 2016 17:16:02 -0700 Subject: 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.
