[PATCH] 2.6.35.4: Fixed simple warning (array subscript is above array bounds)

When I tried to compile, I got the following warning:
fs/xfs/xfs_dir2_block.c: In function ‘xfs_dir2_sf_to_block’:
fs/xfs/xfs_dir2_block.c:1153:26: warning: array subscript is above array bounds
The code (fs/xfs/xfs_dir2_block.c line 1153) is:
dep->name[0] = dep->name[1] = '.';
dep is a pointer to a xfs_dir2_data_entry_t structure where name is defined as:
__u8 name[1]; /* name bytes, no null */
So it is a single element array, name[0] not also name[1] so I got that warning.
Patching is a simple replacement of 1 with 2.
