Subject: [PATCH] drivers/net/wireless/ipw2100: Use the DMA_32BIT_MASK constant
X-Git-Tag: firefly_0821_release~42151^2~9^2~20
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=05743d165be9f0293b4ff67f4e1cf3724eb13e1f;p=firefly-linux-kernel-4.4.55.git

[PATCH] drivers/net/wireless/ipw2100: Use the DMA_32BIT_MASK constant

Use the DMA_32BIT_MASK constant from dma-mapping.h when calling
pci_set_dma_mask() or pci_set_consistent_dma_mask() instead of custom macros.

This patch includes dma-mapping.h explicitly because it caused errors on some
architectures otherwise.  See
