In theory I could change i386 too to return NULL in this case (dma_mask == NULL). But I wonder how how many existing PCMCIA drivers I would break this way? Probably needs more testing at least.

Right now it seems to be (dev->dma_mask != NULL) -Andi - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
