Subject: [PATCH] ieee1394: drivers/ieee1394/pcilynx.c: Use the DMA_32BIT_MASK constant
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=2554bd2a68e2c3ca7f2b953fe2860a9e84a5579a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

[PATCH] ieee1394: drivers/ieee1394/pcilynx.c: 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() These patches include
dma-mapping.h explicitly because it caused errors on some architectures
otherwise.  See http://marc.theaimsgroup.com/?t=108001993000001&r=1&w=2 for
details
