  • ac751efa6   console: rename acquire/release_console_sem() to console_lock/unlock() ... Browse Code »

    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".

  • 950d442ad   drivers/video: release mutex in error handling code ... Browse 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/)

    //
    @@
    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);
    )
    //
