[PATCH 3/7] staging: typec: fusb302: Fix chip->vbus_present init value
From: Guenter Roeck
Date: Tue May 09 2017 - 12:05:10 EST
From: Yueyao Zhu <yueyao.zhu@xxxxxxxxx>
FUSB_REG_STATUS0 & FUSB_REG_STATUS0_VBUSOK = 0x40 & 0x80 is always
zero. Fix the code to what it is intended to be: check the VBUSOK
bit of the value read from address FUSB_REG_STATUS0.
