Subject: [PATCH 5.7.y 1/5] exfat: Set the unused characters of FileName field to the value 0000h

From: "Hyeongseok.Kim" <[email protected]>

Some fsck tool complain that padding part of the FileName field
is not set to the value 0000h. So let's maintain filesystem cleaner,
as exfat's spec. recommendation.
