zalon scsi WARNINGs at kernel/dma/mapping.c:290 dma_free_attrs+0x5c/0x84

[Meelis Roos <mroos-Y27EyoLml9s@public.gmane.org>]

I tried latest Linux on HP A180C (32-bit pa-risc). It works but the Zalon SCSI driver barfs warnings for GSC addon differential scsi board.

The warnings seem to be DMA API related. Packaged 4.19 and self-compiled 5.0.0-rc7 exhibit the same problem.
