This patch fixes the following when compiling a driver module that uses
amba-pl08x:

ERROR: "pl08x_filter_id" [drivers/mtd/nand/lpc32xx_slc.ko] undefined!
ERROR: "pl08x_filter_id" [drivers/mtd/nand/lpc32xx_mlc.ko] undefined!

(drivers/mtd/nand/lpc32xx_* are still in l2-mtd.git)

Done as in:

drivers/dma/coh901318.c
drivers/dma/sirf-dma.c
