From 1fdb4a7907e0290c7fe5ca3346d40782002dec7b Mon Sep 17 00:00:00 2001 From: Kevin Darbyshire-Bryant Date: Sat, 19 Jan 2019 19:42:21 +0000 Subject: [PATCH] kernel: N_BADCLASS: fix macro to actually work - class e support Backport upstream patch: Commit 65cab850f0ee ("net: Allow class-e address assignment via ifconfig ioctl") modified the IN_BADCLASS macro a bit, but unfortunatly one too many '(' characters were added to the line, making any code that used it, not build properly. Also, the macro now compares an unsigned with a signed value, which isn't ok, so fix that up by making both types match properly.
