clang warns about additions on NULL pointers being undefined in C:
security/tomoyo/securityfs_if.c:226:59: warning: arithmetic on a null pointer
treated as a cast from integer to pointer is a GNU extension
[-Wnull-pointer-arithmetic]
securityfs_create_file(name, mode, parent, ((u8 *) NULL) + key,
Change the code to instead use a cast through uintptr_t to avoid
the warning.
Fixes: 9590837b89aa ("Common functions for TOMOYO Linux.")
