From cfbe4dba0d5891faa11bd4e7c1fcdc512aff2f5f Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Sun, 4 Oct 2015 01:09:49 -0700 Subject: [PATCH] i40evf: fix compiler warning of unused variable Compiler complained of an unused variable, which the driver was just using to store the result of a rd32 which is used to clear a register unconditionally. Just drop the unused variable and re-use one.
