Subject: [PATCH 4/4] extcon: axp288: Handle reserved charger-type values better
Date: Fri, 22 Dec 2017 13:36:16 +0100 [thread overview]
Message-ID: <20171222123616.9562-4-hdegoede@redhat.com> (raw)
In-Reply-To: <20171222123616.9562-1-hdegoede@redhat.com>
According to the data sheets all the values not handled in the
switch-case are "reserved". Update the dev_warn message to reflect
this and set the cable-type to EXTCON_CHG_USB_SDP (so max 500mA
current draw) as safe default.
