Hi Saravana,

the issue faced by Jon needs the exact same change but in a different place,
drivers/phy/tegra/xusb.c, which I posted at:
https://lore.kernel.org/all/f979aff2-34f4-4f6d-bb9a-03a02afc4635@notapiano/

So we need two separate patches, one for each issue. Feel free to add that to
this series. (I could send it myself, but I think it makes more sense to keep
them together)

Thanks,
Nícolas
