From 1cb1860d9133ff795cac640b9af4569a2668b45e Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Sun, 25 Sep 2016 14:14:45 -0700 Subject: [PATCH] cxgb4: fix -ve error check on a signed iq iq is unsigned, so the error check for iq < 0 has no effect so errors can slip past this check. Fix this by making iq signed and also get_filter_steerq return a signed int so a -ve error can be returned. Signed-off-by: Colin Ian King Signed-off-by: David S.
