[PATCH 3/5] UBI: fastmap: more nitpicks

From: Artem Bityutskiy <artem.bityutskiy at linux.intel.com>

Again, I feel that this may be annoing for others, but it will make me happier
if I see UBI code having consistent style. After all, people come and go but I
stay maintaining this stuff so I want reading the code to be pleasant for me.
So please, bear with my strange requirements, I will not add this long
explanation anymore, ok? :-)

Anyway, in UBI/UBIFS we try to put identifiers of the same type on one line, if
it fits them.

Also, we do not add blank lines to the identifiers declaration block. If your
function is so huge that it has too many local variables and you need to group
it - fix the function - split it instead.

I've also added a TODO about this. If you could change this globally - it would
make me happier and I'd read your code with more pleasure.
