From 159d3726db12b3476bc59ea0ab0a702103d466b5 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Mon, 2 Jan 2017 11:24:50 +0200 Subject: [PATCH] x86/platform/intel-mid: Rename 'spidev' to 'mrfld_spidev' The current implementation supports only Intel Merrifield platforms. Don't mess with the rest of the Intel MID family by not registering device with wrong properties.
