Subject[PATCH] 2.5.54 kill module.h compiler warnings

Compiling kernel 2.5.54 with CONFIG_MODULES=n results in
tons and tons of the following warnings:

include/linux/module.h:317: warning: statement with no effect
include/linux/module.h:353: warning: statement with no effect

patch-2.5.54 changed *MOD_INC_USE_COUNT from macros to
__deprecated functions, but also dropped the (void) casts
in front of the try_module_get() calls. Without modules,
try_module_get() is the constant 1, hence the warnings.

The patch below silences the warnings by adding back the
missing (void) casts. Works for me.
