Subject: [PATCH] Add firmware for Realtek RTL8192SU, aka rtl8712u, to linux-firmware.

David,
Despite the indication below, this patch file does not actually contain the firmware.
I have sent it this way to avoid spamming mailboxes with the 122 KB binary file, yet
have the revised text of WHENCE available for reviewing.
To obtain everything, please pull from
git://git.kernel.org/pub/scm/linux/kernel/git/lwfinger/r8712u_firmware.git

The source code for the driver with inline firmware is in linux-next in
drivers/staging/rtl8712 and was pushed through GregKH.

No. If you're stating that the *firmware* is under GPL, then we need to
see the source code for the firmware. If not, try another description of
the licence on the firmware.

In the source code originally provided by Realtek, the firmware is inlined in a
header file. Unfortunately, it does not have any license information provided
and starts with
/* Firmware */
static const unsigned char f_array[122328] = {
0x12, 0x87, 0xEC, 0x11, 0x30, 0x00, 0x00, 0x00, 0x08, 0xE8, 0x00, 0x00,
0x50, 0xF5, 0x00, 0x00, 0x30, 0x00, 0x00, 0x00, 0x98, 0xF3, 0x00, 0x00,
The license information that I put into WHENCE is in the source-code file that
contains the MODULE_LICENSE(GPL) statement. As the firmware header file is part
of that set of files, I thought the GPL license would apply to all. Is that not
so? If not, I'm not sure how to proceed.

In theory, the person that added the firmware files to the kernel under the
terms of the GPL or anyone who distributed them before should be able to provide
the source code for the firmware.
If you think that the driver has been developed legally, just ask the author
of the firmware for the source and add it to your patch.
If you don't think it was done correctly, try to get a license for redistributing
the firmware as binary and list the license terms in the WHENCE file.
Hint: some files of the driver contain these "interesting" conditions:
/*

I was the one that added the drive, including the firmware file, to the kernel.
I know the driver was developed legally. I took source files that contain a GPL
license (including the firmware source) from the Realtek public site, cleaned up
the driver, added a copyright for my changes, and got permission from Realtek to
submit the result to the staging directory through Greg K-H. Greg requested a
TODO item to take the firmware currently embedded in a header file with 10,197
lines and 734,033 characters, extract it from the driver, and submit it to
linux-firmware, which is what I'm trying to do now. Once the firmware is
accepted and distros get the new version of linux-firmware, I will submit the
changes that use the standard firmware-loading mechanism to get external
firmware, and delete that large header file. Those changes are now in use on my
system.

That Merello copyright really has little to do with the current driver. As
Realtek included it in their source, I left it in, but consider it to be an
honorary citation.

Ok, so if you have the firmware source, add a proper make file and the source along
with the binary file. You made it sound like the you only had the firmware as
a hexdump, which would not be possible under the GPLv2 section 3, which says
"The source code for a work means the preferred form of the work for making
modifications to it".

That part is fine, what is not fine is the "All rights reserved" portion, which
contradicts the GPL.

Having a patch with the full firmware source and the binary as well seems a bit
large, but I will supply it that way.

Yes, it is schizophrenic, but I left it the way it was.
