From 4e46f271c37415323f2b650d02ef50c87ff8d092 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Tue, 19 Feb 2019 14:57:50 +0800 Subject: [PATCH] usb: typec: mux: Fix unsigned comparison with less than zero The return from the call to fwnode_property_read_u16_array is int, it can be a negative error code however this is being assigned to an size_t variable 'nval', hence the check is always false. Fix this by making 'nval' an int.
