  • fe58103a5   cfag12864b fix ... Browse Code »

    This one-liner patch fixes a bug in drivers/auxdisplay/cfag12864b.c

    At cfag12864b_init(), the driver tries to kalloc some memory in the
    variable cfag12864b_cache.

    Then, as usual, it checks if the call failed. However, it checks
    cfag12864b_buffer instead.

    This patch changes the "cfag12864b_buffer" to "cfag12864b_cache" so the
    correct variable is checked.

    The problem comes when ks0108/cfag12864b are built-in and no parallel port is
    present. ks0108_init() is called first, as it should be, but fails to load
    (as there is no parallel port to use).

    After that, cfag12864b_init() gets called, without knowing anything about
    ks0108 failed, and calls ks0108_writecontrol(), which dereferences an
    uninitialized pointer.

    Init order is OK, I think. The problem is how to stop cfag12864b_init() being
    called if ks0108 failed to load. modprobe does it for us, but, how when
    built-in?

    Add support for auxiliary displays, the ks0108 LCD controller, the
    cfag12864b LCD and adds a framebuffer device: cfag12864bfb.

    - Add a "auxdisplay/" folder in "drivers/" for auxiliary display
    drivers.

    - Add support for the ks0108 LCD Controller as a device driver. (uses
    parport interface)

    - Add support for the cfag12864b LCD as a device driver. (uses ks0108
    LCD Controller driver)

    - Add a framebuffer device called cfag12864bfb. (uses cfag12864b LCD
    driver)

    - Add the usual Documentation, includes, Makefiles, Kconfigs,
    MAINTAINERS, CREDITS...

    - Miguel Ojeda will maintain all the stuff above.
