If anyone has any objections, please let me know. ------------------ From: Adrian Hunter commit eb701ce16a45ed9880897c48f05ee608d77c72e3 upstream. The default for d3_retune is true, but that was not being set in all cases, which results in eMMC errors because re-tuning has not been done. Fix by initializing d3_retune to true.
