I believe all of those patches were completely untested and should first be applied to Linux and then backported, so I won't take this PR.

Why do we require U-Boot driver fixes to be firstly applied to Linux, then backported? Some of them was ported from Linux before, but as time goes I don't think they are a 100% match now. Besides, these 4 fixes are really obvious.

Hello Marek,
I fully understand your point that you want patches first to go upstream. Unfortunately for these 4 patches the patched functions do not exist in Linux drivers/usb. So I am not able to upstream any of these.
Out of the four patches three are just eliminating a superfluous assignment. If you say eliminating this is not worth the effort and risk, I am fine with it.
"usb: xhci-exynos5: correct error checking" https://lists.denx.de/pipermail/u-boot/2018-March/323104.html points to a real inconsistency inside the coding reading the device tree. I must admit I do not have the right board for testing.
drivers/usb/host/ehci-exynos.c has the same problem and should also be fixed.
Best regards
Heinrich

My other concern about this flurry of automated patches is that they were not tested at all, right ? CFR my reply to the faraday hci patch for example.

That's even worse, since that makes it impossible to backport fixes from Linux.

Yes, but then they should be fixed in Linux first and backported to U-Boot , since the whole xhci stack is taken from Linux, right ?
