Subject: drm: Move EXPORT_SYMBOL_FOR_TESTS_ONLY under a separate Kconfig
Git-commit: 6349120ddcbf6267cc4467ee01f852f7bd0cdd42
Patch-mainline: v5.6-rc1
References: jsc#SLE-12680, jsc#SLE-12880, jsc#SLE-12882, jsc#SLE-12883, jsc#SLE-13496, jsc#SLE-15322
Currently, we only export symbols for drm-selftests which are either
compiled as modules or into the main drm builtin. However, if we want to
export symbols from drm.ko for the drivers' selftests, we require a
means of controlling that export separately. So we add a new Kconfig to
determine whether or not the EXPORT_SYMBOL_FOR_TESTS_ONLY() takes
effect.
