From 2250563e2c935d6401a2203be4de4ca2cf0db183 Mon Sep 17 00:00:00 2001 From: "Michael J. Ruhl" Date: Mon, 24 Jul 2017 07:46:06 -0700 Subject: [PATCH] IB/hfi1: Pass the context pointer rather than the index The hfi1_rcvctrl() function receives an index which it then converts to an rcd. Since most functions have the rcd, use that instead. Reviewed-by: Mike Marciniszyn Reviewed-by: Sebastian Sanchez Signed-off-by: Michael J.
