Subject: [PATCH] ethernet: octeontx2: avoid linking objects into multiple modules
From: Arnd Bergmann <arnd@...db.de>
Each object file contains information about which module it gets linked
into, so linking the same file into multiple modules now causes a warning:
scripts/Makefile.build:254: drivers/net/ethernet/marvell/octeontx2/nic/Makefile: otx2_devlink.o is added to multiple modules: rvu_nicpf rvu_nicvf
Change the way that octeontx2 ethernet is built by moving the common
file into a separate module with exported symbols instead.
Signed-off-by: Arnd Bergmann <arnd@...db.de>
