Subject: [PATCH] usb: typec: tcpm: Ignore Vsafe0v in PR_SWAP_SNK_SRC_SOURCE_ON state
Date: Wed, 16 Jun 2021 01:32:06 +0800	[thread overview]
Message-ID: <20210615173206.1646477-1-kyletso@google.com> (raw)

In PR_SWAP_SNK_SRC_SOURCE_ON state, Vsafe0v is expected as well so do
nothing here to avoid state machine going into SNK_UNATTACHED.

Fixes: 28b43d3d746b ("usb: typec: tcpm: Introduce vsafe0v for vbus")
