Amitoj Kaur Chawla 514dd88df7 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)

 x =

|
*pci_map_page(...)
)
 ... when != pci_dma_mapping_error(e1,x)
// </smpl>

README 

This driver is supposed to support:

	Mojave cards (single port PCI Gigabit) both copper and fiber
	Oasis cards (single and dual port PCI-x Gigabit) copper and fiber
	Kalahari cards (dual and quad port PCI-e Gigabit) copper and fiber

The driver was actually tested on Oasis and Kalahari cards.
