From mboxrd@z Thu Jan 1 00:00:00 1970 From: b29396@freescale.com (Dong Aisheng) Date: Mon, 4 Nov 2013 16:38:28 +0800 Subject: [PATCH v2 4/5] mmc: sdhci-esdhc-imx: fix runtime pm unblance issue In-Reply-To: <1383554309-29065-1-git-send-email-b29396@freescale.com> References: <1383554309-29065-1-git-send-email-b29396@freescale.com> Message-ID: <1383554309-29065-5-git-send-email-b29396@freescale.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Since we're using common esdhc_send_command for tuning commands and the core code will call pm_runtime_put after command is finished. So we add a pm_runtime_get_sync here to get the blance.
