Hey Arnd-
I wanted to see if you had any ideas about this problem.
CONFIG_KS8851=y
CONFIG_KS8851_MLL=m
The problem is that 2 drivers share some common code, but in one case
the shared code is builtin and for the other driver it is a loadable
module. The common code is first built as builtin, so it does not have
the "__this_module" symbol.
Thanks.
