From 510a9002348a7d6f2bc8620d6de75d868cefddb9 Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Sun, 5 Jul 2020 22:42:27 +0200 Subject: [PATCH] net: dsa: rtl8366: Pass GENMASK() signed bits Oddly, GENMASK() requires signed bit numbers, so that it can compare them for < 0. If passed an unsigned type, we get warnings about the test never being true. Signed-off-by: Andrew Lunn Reviewed-by: Florian Fainelli Signed-off-by: David S.
