Subject: 2.4.0-test13-pre3 drivers/char/Makefile and CONFIG_DRM_MGA=m


Hello,

When I use 'make menuconfig' on 2.4.0-test13-pre3 to select DRM and the
Matrox DRM driver as a module, I get a .config with CONFIG_DRM=y and
CONFIG_DRM_MGA=m. However, this causes drivers/char/Makefile to skip the
drm subdirectory when compiling modules: its only reference to CONFIG_DRM
is the line 'subdir-$(CONFIG_DRM) += drm' and 'make menuconfig' does not
allow me to select 'm' for CONFIG_DRM.

I don't know enough about the kernel Makefiles to figure out the proper
solution, but I was able to get the modules compiled by adding the line
'mod-subdirs += drm' to drivers/char/Makefile. This is not the proper
solution, I expect, as now 'make modules' will enter the driver/char/drm
subdirectory even if CONFIG_DRM=n.

Cheers,
Wayne
