add consts where appropriate in fs/nls/*
Add const modifiers to a few struct nls_table's member pointers in
include/linux/nls.h and adds a lot of const's in fs/nls/*.c files.
Resulting changes as visible by size:
text data bss dec hex filename
113612 481216 2368 597196 91ccc nls.org/built-in.o
593548 3296 288 597132 91c8c nls/built-in.o
Apparently compiler managed to optimize code a bit better
because of const-ness.
No other changes are made.
