From mboxrd@z Thu Jan 1 00:00:00 1970 From: Sergei Shtylyov Subject: [PATCH 1/2] mmc: skip reclaiming host on mmc_add_card() error Date: Wed, 14 Oct 2015 23:53:03 +0300 Message-ID: <4835546.qgzOJFlmY8@wasted.cogentembedded.com> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: ulf.hansson@linaro.org, linux-mmc@vger.kernel.org Cc: linux-kernel@vger.kernel.org List-Id: linux-mmc@vger.kernel.org There's little sense in releasing the host on mmc_add_card() error immediately after reclaiming it, so reclaim the host only in case of success.
