Subject: [PATCH linux-next v2] arm64: PCI: Introduce pcibios_free_irq() helper function
Date: Thu, 26 Aug 2021 14:04:06 +0800	[thread overview]
Message-ID: <20210826060406.12571-1-yajun.deng@linux.dev> (raw)

pcibios_alloc_irq() will be called in pci_device_probe(), but there
hasn't pcibios_free_irq() in arm64 architecture correspond it.
pcibios_free_irq() is an empty weak function in drivers/pci/pci-driver.c.
So add pcibios_free_irq() for correspond it. This will be called
in pci_device_remove().

====================
v2: remove the change in pcibios_alloc_irq(), and modify the commit log.
====================
