Subject: [PATCH 04/18] sound: fix mixed module-builtin object
From: Masahiro Yamada <masahiroy@...nel.org>
With 'y' and 'm' mixed for CONFIG_SNC_SOC_WCD93{35,4X,8X}, wcd-clsh-v2.o
is linked to module(s) and also to vmlinux even though the expected
CFLAGS are different between builtins and modules.
This is the same situation as fixed by commit 637a642f5ca5 ("zstd:
Fixing mixed module-builtin objects").
Turn helpers in wcd-clsh-v2.o into inline functions.
