[Serge E. Hallyn]

Quoting Geert Uytterhoeven (geert at linux-m68k.org):
> with W=2:
> 
>     security/apparmor/policy_unpack.c: In function ‘unpack_trans_table’:
>     security/apparmor/policy_unpack.c:469: warning: declaration of ‘pos’ shadows a previous local
>     security/apparmor/policy_unpack.c:451: warning: shadowed declaration is here
> 
> Rename the old "pos" to "saved_pos" to fix this.
