Hi all, I see errors like the following in linux next-20181123 when trying to boot a mainline kernel on a LG Nexus 5 phone:
[ 14.495056] mmc1: Card stuck in wrong state! mmcblk1 card_busy_detect status: 0xe00 [ 14.495185] mmc1: cache flush error -110 [ 14.601547] mmc1: Reset 0x1 never completed.

This change was made with the commit: 03864e57770a ("ARM: dts: qcom: msm8974-hammerhead: increase load on l20 for sdhci") Is there a change that I should make in device tree to get the SD card working again on the phone? Thanks, Brian
