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
