[PATCH] cdx: constify bin_attribute callback

[Arnd Bergmann <arnd@kernel.org>]

From: Arnd Bergmann <arnd@arndb.de>

This one was missed in the treewide conversion:

drivers/cdx/cdx.c: In function 'cdx_create_res_attr':
drivers/cdx/cdx.c:773:24: error: assignment to 'int (*)(struct file *, struct kobject *, const struct bin_attribute *, struct vm_area_struct *)' from incompatible pointer type 'int (*)(struct file *, struct kobject *, struct bin_attribute *, struct vm_area_struct *)' [-Wincompatible-pointer-types]
  773 |         res_attr->mmap = cdx_mmap_resource;
      |                        ^

Fixes: 94a20fb9af16 ("sysfs: treewide: constify attribute callback of bin_attribute::mmap()")
