This patches causes a regression on a imx51-babbage running 4.18-rc1:
I get a kernel hang.
If I revert it on top of 4.18-rc1, then it boots fine and USB host is
functional.
I understand this patch fixes a kernel hang for you, so which commit
is responsible for the hang you observe?
It seems this commit fixes a hang for you and causes another hang for me :-)
Any ideas?
Thanks
