From e99a0745bdf8a5f7e3126a686846af4aeb852cc9 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 5 Jul 2016 23:09:07 +0300 Subject: [PATCH] x86/pci, x86/platform/intel_mid_pci: Remove duplicate power off code Intel MID platforms (Moorestown, Medfield, Clovertrail, Merrifield) are sharing the code in the intel_mid_pci.c module. There is no need to power off specific Moorestown devices after the following commit: 5823d0893ec2 ("x86/platform/intel-mid: Add Power Management Unit driver") ... because the condition in mrfld_power_off_dev() is true for any platform from the above list. Remove duplicate power off certain devices on Intel Moorestown and rename the affected functions to show that they are applied to any of Intel MID platforms.
