[PATCH] autofs4 - fix false positive compile error

[Ian Kent]

On strict build environments we can see:

fs/autofs4/inode.c: In function 'autofs4_fill_super':
fs/autofs4/inode.c:312: error: 'pgrp' may be used uninitialized in this
function
make[2]: *** [fs/autofs4/inode.o] Error 1
make[1]: *** [fs/autofs4] Error 2
make: *** [fs] Error 2
make: *** Waiting for unfinished jobs....

This is due to the use of pgrp_set being used to indicate pgrp has
has been set rather than initializing pgrp itself.
