Thanks Stephen, the fix looks correct.

Roger,
It seems you sent two separate patches touching exactly the same files
recently for two different trees. One for memory controllers moving the
NAND ids and second for MTD tree with adding new compatible.
Please don't, instead second should base on the other and these should
go via one tree. This is a non-trivial conflict which could be avoided.


Best regards,
Krzysztof
