The "mem" buffer has "size" bytes. The ">" should be ">=" to prevent
reading one character beyond the end of the array.

Now that %z is standartised in C99 there is no reason to support %Z.
Unlike %L it doesn't even make format strings smaller.
Use BUILD_BUG_ON in a couple ATM drivers.
In case anyone didn't notice lib/vsprintf.o is about half of SLUB which
is in my opinion is quite an achievement. Hopefully this patch inspires
someone else to trim vsprintf.c more.

par->metromem_cmd->args[] is an array of 31 elements of size u16. Here
we have initialized the first "i" elements and want to set the rest to
zero.
The issue here is that ARRAY_SIZE(par->metromem_cmd->args) is 31 and not
32 as in the original code. It means that we set ->csum to zero, but
that is harmless because we immediately set it to the correct value on
the next line.
Still, the buffer overflow upsets static checkers so let's correct the
math.

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.
