kernel compiling problems

Hi,

Sometimes I get errors when compiling the latest staging tree -
recently it happened on the device drivers > mtd module due to
duplicate module_init functions and the build breaks. Do I need to
report them or its handled by some auto build system that takes care
of it.

Also I get errors on CONFIG_DEBUG_SECTION_MISMATCH. Do I need to
report them and to whom ?

Regards.
