From 50e0d28d3808146cc19b0d5564ef4ba9e5bf3846 Mon Sep 17 00:00:00 2001 From: Raju Rangoju Date: Tue, 24 Mar 2020 17:10:00 +0530 Subject: cxgb4/ptp: pass the sign of offset delta in FW CMD cxgb4_ptp_fineadjtime() doesn't pass the signedness of offset delta in FW_PTP_CMD. Fix it by passing correct sign. Signed-off-by: Raju Rangoju Signed-off-by: David S.
