Hi Arnd,

Ahm - this patch should have only be applied if it would have been
possible to commit it before the release of v4.7.

Mainline Patch b5896f6 ("ARM: tegra: Remove commas from unit addresses
on Tegra124") which was introduced during the merge window of v4.8 makes
this patch superfluous and introduces the same error again that we
initially wanted to fix :-)

This patch is only required for stable v4.7.x.

I think the best is to revert it on mainline, as long as stabilization
window is still open.
