Subject: [PATCH] ASoC: sprd: Allow the MCDT driver to build into modules
Git-commit: fd357ec595d36676c239d8d16706a270a961ac32
Patch-mainline: v5.7-rc1
References: jsc#SLE-16518
Change the config to 'tristate' for MCDT driver to allow it to build into
modules, as well as changing to use IS_ENABLED() to validate if need supply
dummy functions when building the MCDT driver as a module.
