Current vendor-prefixes.txt already has "ak" prefix for Asahi Kasei Corp
by ae8c4209af2c(of: Add vendor prefix for Asahi Kasei Corp.)

It went through the appropriate review process. But, almost all
Asahi Kasei chip drivers are using "asahi-kasei" prefix today.
(arch/arm/boot/dts/tegra20-seaboard.dts only is using "ak,ak8975",
 but there are instances of "asahi-kasei,ak8975" in other dts files.
 And drivers/iio/magnetometer/ak8975.c doesn't support "ak,ak8975" prefix)
So, we made a mistake there.

In addition, checkpatch.pl reports WARNING if it is using "asahi-kasei"
prerfix in DT file.
(DT compatible string vendor "asahi-kasei" appears un-documented)

Marking it deprecated and warning with checkpatch is certainly
preferable. So, this patch replace "ak" to "asahi-kasei" in
vendor-prefixes.txt. (and fixup tegra20-seaboard)

OTOH, Asahi Kasei is usually referred to as "AKM", but this patch
doesn't care about it. Because no DT is using that today.

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

It doesn't seem to be ack'd by any of the DT maintainers. Retro-actively
changing a DT vendor name would need that, I think.

Thierry and Alex (both Tegra maintainers) appear to have ack'd it, so it
seems they expect it to go through some tree other than Tegra. Weren't
there a bunch of related patches along with this (e.g. updating relevant
drivers to support both prefixes?) so it was expected this patch would
be applied together with them?

Rob ?
I had sent this patch to him since half-years ago, many times...
Or other maintainer ?

I guess they expected it goes to DT branch (?)
This is only 1 patch. it doesn't have related patch-set

It is in my queue. If the users of it are fine with breaking things,
who am I to argue with them.

It's an i2c device, so it won't break, based on the implementation
we use in the kernel that ignores the vendor part when the part number
matches the i2c driver name.

I also don't think we need to worry about any non-Linux operating
systems on this board that might share the same dts file.

Plus this update is actually changing the board DT file have the ID
which we've always had in the driver, the driver has always used the new
string and never the ak, based one that the device tree is registering.
