Subject: [PATCH] HID: uclogic: avoid linking common code into multiple modules
Date: Wed, 29 May 2024 11:48:05 +0200
Message-Id: <20240529094816.1859073-1-arnd@kernel.org>
Precedence: bulk
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit

From: Arnd Bergmann <arnd@arndb.de>

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@arndb.de>

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.
