| Subject: fat: fix uninitialized variable |
| |
| From: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> |
| |
| commit 963a7f4d3b90ee195b895ca06b95757fcba02d1a upstream. |
| |
| syszbot produced this with a corrupted fs image. In theory, however an IO |
| error would trigger this also. |
| |
| This affects just an error report, so should not be a serious error. |
