From: Roland Dreier <roland@topspin.com>
The last parameter of proc_symlink is usually a "const char *", but the
stub in <linux/proc_fs.h> for CONFIG_PROC_FS=n omits the const and makes
its last parameter a "char *". This causes a warning about discarding
qualifiers for any code that passes something const for that last
parameter.
This patch fixes that up and also, for neatness's sake, makes the stub for
create_proc_read_entry() match the usual prototype more exactly (use
read_proc_t rather than the underlying function pointer type).
