This needed some further rearrangement. Please validate v5 of the patch. Any branch that has the v4 patch should revert that change and freshly re-apply the v5 patch. I hope this simplifies merging into mainline. Verified by 1. rebooting numerous times (no mmc errors, partitions on mmc SD card are properly detected, no hangs upon reboot, i.e., the change appears to work) 2. "cat /sys/kernel/debug/regulator/regulator_summary" now correctly shows regulators, regulator-dummy use count is 1 3. ensuring that no entries for "(null)-SUPPLY' were found in dmesg or /sys Thanks, Christian
