Subject[PATCH] kmalloc() bug in pci-dma.c

After burning my fingers with a similar mistake in one of the patches
that I am working on, I did a quick grep to find out all faulty kmalloc()
calls and found this.

dma_declare_coherent_memory() is calling kmalloc with wrong arguments.
Attached patch fixes this.

Please apply.
