[PATCH 1/9] PCI: Make pcim_release_region() a public function

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

 



pcim_release_region() is the managed counterpart of
pci_release_region(). It can be useful in some cases where drivers want
to manually release a requested region before the driver's remove()
callback is invoked.

Make pcim_release_region() a public function.
