From 1103a631a83408733849b47fa2170cda984df2a3 Mon Sep 17 00:00:00 2001 From: Yanir Lubetkin Date: Sat, 28 Feb 2015 10:10:06 +0000 Subject: [PATCH] e1000e: remove calls to ioremap/unmap for NVM addr Starting I219, the NVM will not be mapped to its own BAR, but to an address region in another bar. The mapping/unmapping is relevant to older HW only.
