Subject: [PATCH v2] ARM: tegra: Correct which USB controller has the UTMI pad registers
Date: Thu, 2 Apr 2015 17:00:42 +0200 [thread overview]
Message-ID: <1427986842-21409-1-git-send-email-tomeu.vizoso@collabora.com> (raw)
In-Reply-To: <551D57E0.7050102@kapsi.fi>
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
