Above mentioned patches were not accepted by the maintainers of generic-phy
and usb. I couldn't get any response on them for quite a long time. So, the
patches could never make it to the mainline.
I can try initiating the entire exercise once again and try to get them merged.

If the network is coming out of the USB 3.0 phy, then definitely you will see
a performance drop.

AFA dwc3-exynos is concerned, there's definitely a resource leak as
pointed out by you.
Please post the suggested patch, adding required people in CC.
