[PATCH 2/2] extcon: ptn5150: Do not print error during probe if nothing is attached

From: Krzysztof Kozlowski
Date: Wed Sep 09 2020 - 12:55:08 EST

The commit af71b7e384cd ("extcon: ptn5150: Check current USB mode when
probing") reused code for checking CC status register in the probe path
to determine what is initially connected. However if nothing is
connected, the CC status register will have 0x0 value and print an error

ptn5150 1-003d: Unknown Port status : 0

This is not an error. Also any other unknown port status values are not
really errors but unhandled cases.
