Subject: [PATCH] staging: qlge: replace deprecated apis pci_dma_*

From: realwakka <realwakka@...il.com>

Replace legacy/depreacted pci_dma_* functions to new dma_* functions.
Also replace PCI_DMA_* macro to DMA* macro.

Signed-off-by: realwakka <realwakka@...il.com>
---

Changes in v2:
- Change ternary operator to if-else for readability.
