From 60d585ad6e64bac87a676df4d941c823360f6ae1 Mon Sep 17 00:00:00 2001 From: Dean Luick Date: Tue, 12 Apr 2016 10:50:35 -0700 Subject: [PATCH] IB/hfi1: Simplify init_qpmap_table() Make init_qpmap_table() easier to understand by simplifying the loop indexing and writing each register when it is "full", removing the need for a follow-on register write.
