From aeae6ad35e973d9c31449de6868ef37ce6b7d05e Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 11 Dec 2018 15:10:43 +0200 Subject: mmc: sdhci-pci: Disable LED control for Intel BYT-based controllers Intel BYT-based controllers do not have a LED signal line. Nevertheless sdhci_led_control() takes more than twice as long as sdhci_send_command(), even though it does nothing. Use the new SDHCI_QUIRK_NO_LED quirk to disable LED control for Intel BYT-based controllers.
