I forgot to mention, Boris has done more cleanup which breaks your
patches, please have a look at the following commits in the nand/next
branch, they will force you to do some light rework to get the driver
building (especially, you should not export the ->select_chip hook anymore):

7a08dbaedd36 mtd: rawnand: Move ->setup_data_interface() to nand_controller_ops
f2abfeb2078b mtd: rawnand: Move the ->exec_op() method to nand_controller_ops
7d6c37e90cf9 mtd: rawnand: Deprecate the ->select_chip() hook
1770022ffa85 mtd: rawnand: ams-delta: Stop implementing ->select_chip()
653c57c7da08 mtd: rawnand: vf610: Stop implementing ->select_chip()
2ace451cae22 mtd: rawnand: tegra: Stop implementing ->select_chip()
b25251414f6e mtd: rawnand: marvell: Stop implementing ->select_chip()
550b9fc4e3af mtd: rawnand: fsmc: Stop implementing ->select_chip()
02b4a52604a4 mtd: rawnand: Make ->select_chip() optional when ->exec_op() is implemented
ae2294b10b0f mtd: rawnand: Pass the CS line to be selected in struct nand_operation
1d0178593d14 mtd: rawnand: Add nand_[de]select_target() helpers

Thanks,
