Jiri Kosina 2f43f8749e HID: remove Paul Walmsley's copyright from places where it shouldn't be
Paul Walmsley has implemented dynamic quirk handling back in 2007 through
commits:

2eb5dc30eb ("USB HID: encapsulate quirk handling into hid-quirks.c")
8222fbe67c ("USB HID: clarify static quirk handling as squirks")
8cef908235 ("USB HID: add support for dynamically-created quirks")
876b9276b9 ("USB HID: add 'quirks' module parameter")

and as such, his copyright rightly belongs to
drivers/hid/usbhid/hid-quirks.c file.

However when generic HID code has been converted to bus and individual
quirks separated out to individual drivers on the bus, the copyright has
been blindly transfered into all the tiny drivers, which actually don't
contain any of Pauls' copyrighted code.

Remove the copyright from those sub-drivers.

* [0419:0001] Samsung IrDA remote controller (reports as Cypress USB Mouse).
* various hid report fixups for different variants.
*
* [0419:0600] Creative Desktop Wireless 6000 keyboard/mouse combo
* several key mappings used from the consumer usage page
* deviate from the USB HUT 1.12 standard.

* There are several variants for 0419:0001:
*
* 1. 184 byte report descriptor
* Vendor specific report #4 has a size of 48 bit,
* and therefore is not accepted when inspecting the descriptors.
* As a workaround we reinterpret the report as:
* Variable type, count 6, size 8 bit, log. maximum 255
* The burden to reconstruct the data is moved into user space.
*
* 2. 203 byte report descriptor
* Report #4 has an array field with logical range 0..18 instead of 1..15.
*
* 3. 135 byte report descriptor
* Report #4 has an array field with logical range 0..17 instead of 1..14.
*
* 4. 171 byte report descriptor
* Report #3 has an array field with logical range 0..1 instead of 1..3.
