[patch 14/16] PCI/MSI: Rename __read_msi_msg() to __pci_read_msi_msg()

[Thomas Gleixner <tglx@linutronix.de>]

[-- Attachment #1: rfc-part4-v1-11-17-pci-msi-rename-__read_msi_msg-as-__pci_read_msi_msg.patch --]
[-- Type: text/plain, Size: 3439 bytes --]

Rename __read_msi_msg() to __pci_read_msi_msg() and kill unused
read_msi_msg(). It's a preparation to separate generic MSI code from
PCI core.
