linux-firmware.git does not contain firmware for all drivers. _At least_
zd1211rw [1], atmel [2] and ipw2x00 [3] are out of the tree.

Yeah, don't forget p54. It needs out-of-tree firmwares as well.

But what about iwlegacy? Isn't that another candidate that would fit both
requirements (no recent firmware update, firmware in linux-firmware.git) ?

[PATCH] carl9170: Clarify kconfig text

[Lauri Kasanen]

The previous text was confusing, leading readers to think this
driver was a duplicate, and so didn't need to be enabled.

After the removal of the older staging driver, this is the only
driver in mainline for these devices.

Why even mention anything about a "special firmware" as the firmware is
already available from linux-firmware.git? That's default location for
all firmware images and I think most, if not all, distros should have it
available. So wouldn't it be better not to mention anything about
firmware at all?

Yes and no. 1.9.6 is in linux-firmware.git. I've tried to add 1.9.9 too
but that failed.

Sure, but this could be a different patch then. I think Intel devices 
(iwlwifi, iwlegacy and ipw2x00) have a similar text about "download
firmware from this device from our homepage here" too. So if we want,
we can remove them altogether?

Rick's comment makes sense to me, better just to provide the latest
version. No need to unnecessary confuse the users. And if someone really
wants to use an older version that she can retrieve it from the git
history.

So iwlwifi now has:

	  In order to use this driver, you will need a firmware
	  image for it. You can obtain the microcode from:

	          <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.

Maybe that could be changed to mention about the wiki page in general:

	  The driver has a wiki page at:

	          <http://wireless.kernel.org/en/users/Drivers/iwlwifi>.

But I know iwlwifi updates the firmware images pretty often so Emmanuel
might see this differently.

Part of the fun here is that firmware is GPLv2. The linux-firmware.git has
to point to or add the firmware source to their tree. They have added every
single source file to it.... instead of "packaging" it in a tar.bz2/gz/xz
like you normally do for release sources.

Yeah, that's more work. I get that. But I'm still not understanding
what's the actual problem which prevents us from updating carl9170
firmware in linux-firmware.
