Subject: [PATCH] staging: qlge: replace deprecated apis pci_dma_*
Date:   Tue, 21 Apr 2020 00:40:09 +0900
Message-Id: <20200420154009.21161-1-realwakka@gmail.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

From: realwakka <realwakka@gmail.com>

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

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

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