From 3ce3026a0967350812b8cf246709b65384d2a336 Mon Sep 17 00:00:00 2001 From: Uri Mashiach Date: Sun, 21 May 2017 17:00:52 +0300 Subject: [PATCH] net: usb: mcs7830: fix non-DM ingress path The mcs7830_recv() (non-DM) function discards good packets and tries to process "bad" packets due to incorrect test condition. Fix the condition and return the proper value as described in function doc.
