[PATCH v2] ARM: tegra: Correct which USB controller has the UTMI pad registers

From: Tomeu Vizoso
Date: Thu Apr 02 2015 - 11:01:23 EST


It should be the first controller, not the second.

This broke USB after 6261b06 ("regulator: Defer lookup of supply to
regulator_get"), because it changed the order in which the controllers
were probed.

The fix for this issue was suggested by Mikko Perttunen.

I think that the line numbers should be enough in this case, as I expect this to be merged soon, but just in case I'm sending the same patch with plenty of context.

Regards,

Tomeu
