[PATCH 06/18] autofs - remove ino free in autofs4_dir_symlink()

[Ian Kent]

The inode allocation failure case in autofs4_dir_symlink() frees
the autofs dentry info of the dentry without setting ->d_fsdata to
NULL.

That could lead to a double free so just get rid of the free and
leave it to ->d_release().
