Subject: [PATCH 10/18] EDAC: i10nm, skx: fix mixed module-builtin object
With CONFIG_EDAC_SKX=m and CONFIG_EDAC_I10NM=y (or vice versa),
skx_common.o are linked to a module and also to vmlinux even though
the expected CFLAGS are different between builtins and modules:
> scripts/Makefile.build:252: ./drivers/edac/Makefile: skx_common.o
> is added to multiple modules: i10nm_edac skx_edac
This is the same situation as fixed by commit 637a642f5ca5 ("zstd:
Fixing mixed module-builtin objects").
Introduce the new module, skx_edac_common, to provide the common
functions to skx_edac and i10nm_edac. skx_adxl_{get,put}() loose
their __init/__exit annotations in order to become exportable.
Fixes: d4dc89d069aa ("EDAC, i10nm: Add a driver for Intel 10nm server processors")
Suggested-by: Masahiro Yamada <masahiroy@...nel.org>
