Subject: s390/pci: Use for_pci_msi_entry() to access MSI device list
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=df516f4278c154f5bb5e594fd54c2b0cb0af7a7c;p=linux-beck.git

s390/pci: Use for_pci_msi_entry() to access MSI device list

Use accessor for_each_pci_msi_entry() to access MSI device list, so we could
easily move msi_list from struct pci_dev into struct device later.
