b4a1ed0cd1 fbdev: make FB_BACKLIGHT a tristate
BACKLIGHT_CLASS_DEVICE is already tristate, but a dependency
FB_BACKLIGHT prevents it from being built as a module.  There
doesn't seem to be any particularly good reason for this, so
switch FB_BACKLIGHT over to tristate.

c9e6a36492 fbcon: Add fbcon_rotate_hint to struct fb_info
On some hardware the LCD panel is not mounted upright in the casing,
but upside-down or rotated 90 degrees. In this case we want the console
to automatically be rotated to compensate.

The fbdev-driver may know about the need to rotate. Add a new
fbcon_rotate_hint field to struct fb_info, which gets initialized to -1.
If the fbdev-driver knows that some sort of rotation is necessary then
it can set this field to a FB_ROTATE_* value to tell the fbcon console
driver to rotate the console.

b4df20474f fbdev: fix snprintf() limit in show_bl_curve()
The limit should be "PAGE_SIZE - len" instead of PAGE_SIZE.  Also let's
use scnprintf() because snprintf() returns the number of bytes which
would have been printed if there were space and scnprintf() returns the
number of bytes actually printed.

I don't think we are ever going to actually hit this limit in real life.

30296f6115 video: fbdev: use %*ph specifier to dump small buffers
Instead of dereference each byte let's use %*ph specifier in the printk()
calls.

19757fc843 fbdev: move fbdev core files to separate directory
Instead of having fbdev framework core files at the root fbdev
directory, mixed with random fbdev device drivers, move the fbdev core
files to a separate core directory. This makes it much clearer which of
the files are actually part of the fbdev framework, and which are part
of device drivers.
