5.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx>
[ Upstream commit 9931f7d5d251882a147cc5811060097df43e79f5 ]
the Intel kbuild bot reports a link failure when IOSF_MBI is built-in
but the Merrifield driver is configured as a module. The
soc-intel-quirks.h is included for Merrifield platforms, but IOSF_MBI
is not selected for that platform.
ld.lld: error: undefined symbol: iosf_mbi_read
>>> referenced by atom.c
>>> sound/soc/sof/intel/atom.o:(atom_machine_select) in archive vmlinux.a
This patch forces the use of the fallback static inline when IOSF_MBI is not reachable.
