From 07c161bcd7ff6d119f828402a776c9e43a50a851 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Wed, 29 Jun 2016 16:24:38 +0300 Subject: [PATCH] mmc: sdhci: sdhci_execute_tuning() must delete timer sdhci_send_command() starts a timer to catch cases where the host controller fails. The timer is normally deleted when the request completes, but in the case of sdhci_execute_tuning() the request is handled differently and the timer is left running. This goes unnoticed because tuning is done before another command so the timer gets reset then. That should not be relied upon, so make sdhci_execute_tuning() delete the timer.
