I don't know if this is the same failure or just similar:

ERROR: "regmap_exit" [drivers/mfd/wm8400-core.ko] undefined!
ERROR: "regmap_bulk_read" [drivers/mfd/wm8400-core.ko] undefined!
ERROR: "regmap_read" [drivers/mfd/wm8400-core.ko] undefined!
ERROR: "regmap_init_i2c" [drivers/mfd/wm8400-core.ko] undefined!
ERROR: "regmap_raw_read" [drivers/mfd/wm8400-core.ko] undefined!
ERROR: "regmap_write" [drivers/mfd/wm8400-core.ko] undefined!

Maybe MFD_WM8400 needs to select REGMAP_I2C ?
