The arm64 gcc-9 release warns about a change in the calling
conventions:
drivers/video/fbdev/mx3fb.c: In function 'sdc_init_panel':
drivers/video/fbdev/mx3fb.c:506:12: note: parameter passing for argument of type 'struct ipu_di_signal_cfg' changed in GCC 9.1
506 | static int sdc_init_panel(struct mx3fb_data *mx3fb, enum ipu_panel panel,
| ^~~~~~~~~~~~~~
drivers/video/fbdev/mx3fb.c: In function '__set_par':
drivers/video/fbdev/mx3fb.c:848:7: note: parameter passing for argument of type 'struct ipu_di_signal_cfg' changed in GCC 9.1
Change the file to just pass the struct by reference, which is
unambiguous and avoids the warning.

Now that the fbops member of struct fb_info is const, we can start
making the ops const as well.
This does not cover all drivers; some actually modify the fbops struct,
for example to adjust for different configurations, and others do more
involved things that I'd rather not touch in practically obsolete
drivers. Mostly this is the low hanging fruit where we can add "const"
and be done with it.
v3:
- un-constify atyfb, mb862xx, nvidia and uvesabf (0day)
v2:
- fix typo (Christophe de Dinechin)
- use "static const" instead of "const static" in mx3fb.c
- also constify smscufx.c

%ul was probably meant as %lu since the former would print
an unsigned value and a letter l.
But in fact the whole value we are printing in u32 anyway, so
we don't need the format to be long. Therefore just drop the l
altogether.

Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.
Build tested successfully with allmodconfig.
The following Coccinelle SmPL patch was used for this simple
transformation:
@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@
-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)
@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@
-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)
@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@
-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)
We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

Here's the set of driver core patches for 3.19-rc1.
They are dominated by the removal of the .owner field in platform
drivers. They touch a lot of files, but they are "simple" changes, just
removing a line in a structure.
Other than that, a few minor driver core and debugfs changes. There are
some ath9k patches coming in through this tree that have been acked by
the wireless maintainers as they relied on the debugfs changes.
Everything has been in linux-next for a while.

The backlight_device_unregister() function tests whether its argument is NULL
and then returns immediately. Thus the test around the call is not needed.
This issue was detected by using the Coccinelle software.

The drivers/video directory is a mess. It contains generic video related
files, directories for backlight, console, linux logo, lots of fbdev
device drivers, fbdev framework files.
Make some order into the chaos by creating drivers/video/fbdev
directory, and move all fbdev related files there.
No functionality is changed, although I guess it is possible that some
subtle Makefile build order related issue could be created by this
patch.
