Subject: Re: [PATCH v5][resend v4] of: replace Asahi Kasei Corp vendor prefix


Hi Stephen, Olof, Arnd, Rob, Andrew

I'm sending this "of: replace Asahi Kasei Corp vendor prefix" during
half-year (since Jun 2014) , many times. But, no-one care it.
I don't know who is the best maintainer.
 - Stephen : because it has Tegra ?
 - Olof    : because it has Tegra (= ARM) ?
 - Arnd    : because it has Tegra (= ARM) ?
 - Matthias: because it has Tegra (= ARM SoC) ?
 - Rob     : because DT ?
 - Andrew  : Last chance ?

But, could you please care this patch ?
I will re-send it again
