[PATCH 5.10 182/509] PCI: Add pci_clear_master() stub for non-CONFIG_PCI

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Sui Jingfeng <suijingfeng@xxxxxxxxxxx>

[ Upstream commit 2aa5ac633259843f656eb6ecff4cf01e8e810c5e ]

Add a pci_clear_master() stub when CONFIG_PCI is not set so drivers that
support both PCI and platform devices don't need #ifdefs or extra Kconfig
symbols for the PCI parts.
