From c024c554aeaf6197a1869fdc79c190139182203a Mon Sep 17 00:00:00 2001 From: Dean Luick Date: Mon, 11 Jan 2016 18:30:57 -0500 Subject: [PATCH] staging/hfi1: Remove unneeded variable index The variable "index" increments the same as dd->ndevcntrs. Just use the later. Remove uneeded usage of "index" in the fill loop - it is not used there or later in the function.
