Agree, sorry about this.

This HSU_DMA shouldn't even be a user selectable symbol, they should be
selected the HSU_PCI driver (which has a help text) and this already done by
HSU_PCI

Linus,
Please apply this for fixing it. I have noticed few other places as well, will add
them on my dmaengine pull request and send.

Thanks

Subject: [PATCH] dmaengine: hsu: don't prompt for hsu_core part

HSU_DMA is selected by the HSU_DMA_PCI driver, this should be user selected
so remove the user prompt for this
