From: Konrad Rzeszutek Wilk Date: Wed, 3 Dec 2014 21:40:31 +0000 (-0500) Subject: PCI: Expose pci_load_saved_state for public consumption. X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=98d9b271250bd83337e3ed66d63e7deefcda8712;p=linux-beck.git PCI: Expose pci_load_saved_state for public consumption. We have the pci_load_and_free_saved_state, and pci_store_saved_state but are missing the functionality to just load the state multiple times in the PCI device without having to free/save the state. This patch makes it possible to use this function.
