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.
