Bartlomiej Zolnierkiewicz 0adcdbcb17 video: fbdev: don't print error message on framebuffer_alloc() failure
framebuffer_alloc() can fail only on kzalloc() memory allocation
failure and since kzalloc() will print error message in such case
we can omit printing extra error message in drivers (which BTW is
what the majority of framebuffer_alloc() users is doing already).

Make these const as they are not modified anywhere.

Bhumika Goyal 799b88deec video: fbdev: annotate fb_fix_screeninfo with const and __initconst
Make these const as they are only used during a copy operation.
Some structures are used as a copy operation inside __init functions, so
make them const and replace __initdata with __initconst to avoid section
conflict error.

Dmitry Torokhov 982711ccb0 video: fbdev: pmag-ba-fb: remove incorrect __exit markups
Even if bus is not hot-pluggable, the devices can be unbound from the
driver via sysfs, so we should not be using __exit annotations on
remove() methods. The only exception is drivers registered with
platform_driver_probe() which specifically disables sysfs bind/unbind
attributes.

Maciej W. Rozycki 879e5a0df6 video: fbdev: pmag-ba-fb: Remove bad `__init' annotation
Fix:

WARNING: drivers/video/fbdev/pmag-ba-fb.o(.text+0x308): Section mismatch in reference from the function pmagbafb_probe() to the function .init.text:pmagbafb_erase_cursor()
The function pmagbafb_probe()
references the function __init pmagbafb_erase_cursor().
This is often because pmagbafb_probe lacks a __init
annotation or the annotation of pmagbafb_erase_cursor is wrong.

-- a fallout from a missed update from commit 9625b51350 ("VIDEO: 
PMAG-BA: Fix section mismatch") and then commit 48c68c4f1b ("Drivers: 
video: remove __dev* attributes.")

Maciej W. Rozycki af22f647b4 video: fbdev: pmag-ba-fb: Fix the lower margin size
According to the board specification[1] the width of the vertical sync
front porch is 12 pixels or the same as the width of the horizontal sync
front porch.  This in turn means the size of the lower margin is 0,
because the vertical sync starts as soon as the start of the horizontal
sync terminates the last line.

Tomi Valkeinen f7018c2135 video: move fbdev to drivers/video/fbdev
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.
