Subject: [char-misc-next 0/7] mei: csc: support controller with separate PCI device

Intel PCI driver for chassis controller embedded in Intel graphics
devices.

An MEI device here called CSC can be embedded in discrete
Intel graphics devices having separate PCI device, to support a range
of chassis tasks such as graphics card firmware update and security
tasks.

First five patches are cleanups and preparations.
Then the new component added and additional fix for power management
for this new component only.

Alexander Usyskin (7):
  mei: me: use PCI_DEVICE_DATA macro
  mei: fix idle print specifiers
  mei: me: move trace into firmware status read
  mei: trace: print return value of pci_cfg_read
  mei: convert PCI error to common errno
  mei: csc: support controller with separate PCI device
  mei: csc: wake device while reading firmware status
