From f21949c1496807571ed3d09ed22e0ebeaec3e643 Mon Sep 17 00:00:00 2001 From: Alex Williamson Date: Wed, 20 Apr 2022 14:45:05 -0600 Subject: PCI/doc: Update obsolete pci_set_dma_mask() references The function is dma_set_mask(), fix a missed instance of the old pci_set_dma_mask() and a reference to a function that doesn't exist. Fixes: 05b0ebd06ae6 ("PCI/doc: cleanup references to the legacy PCI DMA API") Link: https://lore.kernel.org/r/165048747271.2959320.13475081883467312497.stgit@omen Signed-off-by: Alex Williamson Signed-off-by: Bjorn Helgaas Reviewed-by: Christoph Hellwig --- Documentation/PCI/pci.rst | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'Documentation/PCI') diff --git a/Documentation/PCI/pci.rst b/Documentation/PCI/pci.rst index 67a850b55617..cced568d78e9 100644 --- a/Documentation/PCI/pci.rst +++ b/Documentation/PCI/pci.rst @@ -273,12 +273,12 @@ Set the DMA mask size While all drivers should explicitly indicate the DMA capability (e.g. 32 or 64 bit) of the PCI bus master, devices with more than 32-bit bus master capability for streaming data need the driver -to "register" this capability by calling pci_set_dma_mask() with +to "register" this capability by calling dma_set_mask() with appropriate parameters.
