From d8b7d6b7f956eac49e9753ac6786ac4e53e075c3 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 21 Mar 2016 14:17:00 +0100 Subject: [PATCH] mmc: mmci: Remove redundant runtime PM calls Commit 9250aea76bfc ("mmc: core: Enable runtime PM management of host devices"), made some calls to the runtime PM API from the driver redundant. Especially those which deals with runtime PM reference counting, so let's remove them.
