a35a9b79dd arkfb: use display information in info not in var for panning
We must not use any information in the passed var besides xoffset,
yoffset and vmode as otherwise applications might abuse it.

ac751efa6a console: rename acquire/release_console_sem() to console_lock/unlock()
The -rt patches change the console_semaphore to console_mutex.  As a
result, a quite large chunk of the patches changes all
acquire/release_console_sem() to acquire/release_console_mutex()

This commit makes things use more neutral function names which dont make
implications about the underlying lock.

The only real change is the return value of console_trylock which is
inverted from try_acquire_console_sem()

This patch also paves the way to switching console_sem from a semaphore to
a mutex.

      fbdev: framebuffer_alloc() fixes

      Correct the dev arg of framebuffer_alloc() in arkfb, s3fb and vt8623fb.

causes a null-pointer deref because "info->dev is NULL, info was just
kzallocated".

950d442ad0 drivers/video: release mutex in error handling code
The mutex is released on a successful return, so it would seem that it
should be released on an error return as well.

The semantic patch finds this problem is as follows:
(http://www.emn.fr/x-info/coccinelle/)

// <smpl>
@@
expression l;
@@

mutex_lock(l);
... when != mutex_unlock(l)
    when any
    when strict
(
if (...) { ... when != mutex_unlock(l)
+   mutex_unlock(l);
    return ...;
}
|
mutex_unlock(l);
)
// </smpl>
