Subject: [PATCH] drm/mipi-dsi: Allow to build drm-mipi-dsi as a module
The drm-mipi-dsi driver has been only built-in although this isn't
strictly required to be so. Since it's referred by lots of DRM
drivers nowadays, most of distro kernels include the driver as
built-in as a result, even though many systems don't need it at all.
This patch fixes Kconfig to allow drm-mipi-dsi driver built as a
module, so that we can save footprint on systems without such DRM
drivers. The probe order is managed by the module dependency, and
postcore_initcall() works just fine as a module init call.
