staging: slicoss: Add error check for pci_map_single
Currently, DMA mapping failure is not detected, causing the hardware
to attempt a DMA from an invalid address.
This patch adds the corresponding error check for pci_map_single i.e.
pci_dma_mapping_error.
Problem found using the following Coccinelle semantic patch:
// <smpl>
@@
expression e1;
identifier x;
@@
x=
(
*dma_map_single(...)
|
*dma_map_page(...)
)
... when != dma_mapping_error(e1,x)
