Subject: remove pci_dma_* abuses and workarounds
Date: Tue, 9 Jan 2018 21:39:36 +0100 [thread overview]
Message-ID: <20180109203939.5930-1-hch@lst.de> (raw)
Back before the dawn of time pci_dma_* with a NULL pci_dev argument
was used for all kinds of things, e.g. dma mapping for non-PCI
devices. All this has been long removed, but it turns out we
still care for a NULL pci_dev in the wrappers, and we still have
two odd USB drivers that use pci_dma_alloc_consistent for allocating
memory while ignoring the dma_addr_t entirely.
This series switches the two drivers to use plain kzalloc and then
removes the handling of the NULL pci_dev in the pci_dma_* wrappers.
