[PATCH] HID: uclogic: avoid linking common code into multiple modules
From: Arnd Bergmann
Date: Wed May 29 2024 - 05:49:15 EST
From: Arnd Bergmann <arnd@xxxxxxxx>
The hid-uclogic-params.o and hid-uclogic-rdesc.o files are linked
into both the driver module and the unit test, which triggers a
W=1 warning:
scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-rdesc.o is added to multiple modules: hid-uclogic hid-uclogic-test
scripts/Makefile.build:236: drivers/hid/Makefile: hid-uclogic-params.o is added to multiple modules: hid-uclogic hid-uclogic-test
Avoids this by moving these two files into a separate module
that is used by the driver and the unit test.
Signed-off-by: Arnd Bergmann <arnd@xxxxxxxx>

I have made patches for all such warnings in the tree, this is one I'm not
sure about, maybe there is a better fix.
