[PATCH -next 06/11] remove CONFIG_KMOD from fs

[Johannes Berg]

Just always compile the code when the kernel is modular.
Convert load_nls to use try_then_request_module to tidy
up the code.

Signed-off-by: Johannes Berg <johannes@xxxxxxxxxxxxxxxx>
---
v2: fix "unused variable" warning pointed out by Adrian Bunk
    by just using try_then_request_module() for load_nls().
