Subject[PATCH 4.6 037/203] extcon: palmas: Fix boot up state of VBUS when using GPIO detection
Date
4.6-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@ti.com>

commit 62e6d1e59c77316768a663d1328390b4cd33801f upstream.

If USB cable is connected prior to boot, we don't get any interrupts
so we must manually check the VBUS state and report it during probe.
If we don't do it then USB controller will never know that peripheral
cable was connected till the user unplugs and replugs the cable.

Fixes: b7aad8e2685b ("extcon: palmas: Add the support for VBUS detection by using GPIO")
