[Q] max11801 licensing terms

[Q] max11801 licensing terms

[Brian Foster]

Zhang Jiejing,

 In “[PATCH V2] input: add maxim max11801 resistance touchscreen
 controller driver” (commit 4203306506ebe4eaaa84a2cbd7c1eb2fc0128faa),

    http://www.spinics.net/lists/linux-input/msg14881.html

 there is a licensing statement my colleagues and I
 do not understand:

     * Based on mcs5000_ts.c
     *
     * This program is free software; you can redistribute it and/or modify
     * it under the terms of the GNU General Public License as published by
     * the Free Software Foundation; either version 2 of the License.
   ...
    MODULE_LICENSE("GPL");

 What does “either version 2 of the License.” mean?
 Either GPLv2 or what?
 The "GPL" MODULE_LICENSE implies what is meant is
 either GPLv2 or a later GPL version; please see
 ‘include/linux/module.h’:

     * The following license idents are currently accepted as indicating free
     * software modules
     *
     *      "GPL"                           [GNU Public License v2 or later]
     *      "GPL v2"                        [GNU Public License v2]

 The original statement in ‘mcs5000_ts.c’ (from Joonyoung Shim,
 whom I've CC-ed) is the usual (reformatted to avoid long lines):

     * This program is free software; you can redistribute it and/or modify
     * it under the terms of the GNU General Public License as published by
     * the Free Software Foundation; either version 2 of the License, or (at
     * your option) any later version.

 Could you please clarify exactly what ‘max11801_ts.c’ licensing
 terms are?  Thanks!

cheers,
        -blf-

Hi Brian Foster,

>     * Based on mcs5000_ts.c
I have referenced mcs5000_ts.c source code when writing this driver,
but I don't think it's a big deal, I really reference lots of files.

Yes, I think it means GPLv2, I'm not really not very care about these
license, just copy other files under driver/input/ directory.

Does it cause trouble in your side?

mcs5000_ts.c (and m97xx-core.c it was derived from) are GPLv2 or later
so max11801_ts.c shoudl folow the same licensing terms, but it seems the
statement was truncated.

Jiejing, could you please send me a patch restoring the proper wording
so there won't be any confusion in the future?

Thanks!
