This regression is listed on
https://linux-regtracking.leemhuis.info/regzbot/mainline/ as being
caused by
https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=master&id=610fa91d9863
("PCI: imx6: Assert PERST# before enabling regulators") but I can't
find any bisect or other report that specifically points to
610fa91d9863.
Can somebody confirm that reverting 610fa91d9863 fixes this
regression, or at least that 610fa91d9863^ works and 610fa91d9863
fails?
