Subject: usb: typec: ucsi: Clear EVENT_PENDING bit if ucsi_send_command fails
From: Prashanth K <quic_prashk@xxxxxxxxxxx>
commit a00e197daec52bcd955e118f5f57d706da5bfe50 upstream.
Currently if ucsi_send_command() fails, then we bail out without
clearing EVENT_PENDING flag. So when the next connector change
event comes, ucsi_connector_change() won't queue the con->work,
because of which none of the new events will be processed.
Fix this by clearing EVENT_PENDING flag if ucsi_send_command()
fails.
