From 22feda47b574c2854cc1a8447a2ae18598752375 Mon Sep 17 00:00:00 2001 From: "Gustavo A. R. Silva" Date: Mon, 18 Mar 2019 09:50:24 -0500 Subject: [PATCH] usb: usb251xb: Remove unnecessary comparison of unsigned integer with >= 0 There is no need to compare *port* with >= 0 because such comparison of an unsigned value is always true. Fix this by removing such comparison.
