fat: gcc 4.3 warning fix
This patch fixes the following warnings. fs/fat/dir.c: In function 'fat_parse_long': include/linux/msdos_fs.h:294: warning: array subscript is above array bounds include/linux/msdos_fs.h:295: warning: array subscript is above array bounds include/linux/msdos_fs.h:295: warning: array subscript is above array bounds The ->name is defined as "name[8], ext[3]", but fat_checksum() uses those as name[11]. There is no actual problem, but it's not a good manner.
