Subject: [PATCH] Fix the warning related to type check in kfifo.h
In d096f3b046, typecheck() replace the original code to check the type
mismatch for kfifo related macros.
After this patch, there shows several warnings. This reason is the original
code use the assignment to check the type. When the left value is a type of
"void *", then there is no warning. This type of mismatch can be detected by
typecheck() macro.
This patch fix the warnings detected by the typecheck() macro.
1. kfifo_in() second parameter should be type "const void *"
1. kfifo_out() second parameter should by type "void *"
3. kfifo_out_locked() second parameter should be type "void *"
4. kfifo_in_locked() second parameter should be type "const void *"
