| Subject: mtd: nuc900_nand: NULL dereference in nuc900_nand_enable() |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| commit c69dbbf3335a21aae74376d7e5db50a486d52439 upstream. |
| |
| Instead of writing to "nand->reg + REG_FMICSR" we write to "REG_FMICSR" |
| which is NULL and not a valid register. |
| |
| Fixes: 8bff82cbc308 ('mtd: add nand support for w90p910 (v2)') |
