Hi Linus (again),
It's been one of those weeks, and I somehow managed to forget the
actual newsworthy item in this fixes pull. Ben Skeggs is stepping away
from nouveau and Red Hat for personal reasons, he'll be missed and we
intend to fill the gaps in the upcoming time with Danilo and Lyude
Since commit ab78029ecc34 ("drivers/pinctrl: grab default handles from
device core"), we can rely on device core for setting the default pins.

Only PowerPC's fb_pgprotect() needs the file argument, although
the implementation in either phys_mem_access_prot() or
pci_phys_mem_access_prot() does not use it. Pass NULL to the internal
helper in preparation of further updates. A later patch will remove
the file parameter from fb_pgprotect().
Clean up and rename fb_pgprotect() to work without struct file. Then
refactor the implementation for PowerPC. This change has been discussed
at [1] in the context of refactoring fbdev's mmap code.
The first two patches update fbdev and replace fbdev's fb_pgprotect()
with pgprot_framebuffer() on
Rename the fbdev mmap helper fb_pgprotect() to pgprot_framebuffer().
The helper sets VMA page-access flags for framebuffers in device I/O
memory.
Also clean up the helper's parameters and return value. Instead of
the VMA instance, pass the individial parameters separately: existing
page-access
Fix coding style. No functional changes.

Remove 'file' parameter from struct machdep_calls.phys_mem_access_prot
and its implementation in pci_phys_mem_access_prot(). The file is not
used on PowerPC. By removing it, a later patch can simplify fbdev's
mmap code, which uses phys_mem_access_prot() on PowerPC.
