Subject: [MTD] NAND Fix platform structure and NDFC driver
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=8be834f76291fdcc0614cb84926c6910b9f2ecbc;p=deliverable%2Flinux.git

[MTD] NAND Fix platform structure and NDFC driver

The platform structure was lacking an oobinfo field.
The NDFC driver had some remains from another tree.
