From aad559c21d7b536444701cb798100d33ff027f70 Mon Sep 17 00:00:00 2001 From: Dasaratharaman Chandramouli Date: Sun, 9 Apr 2017 10:16:15 -0700 Subject: [PATCH] IB/hfi1: Rename hdr2sc to hfi1_9B_get_sc5 The function really returned the 5-bit sc value from the header and rhf. hdr2sc didn't quite describe what it did.
