    SubjectDell Studio 1555 eject key does not work ( small patch to fix included )

    Pressing the eject key on my Dell Studio 1555 does not work and dmesg produces
    this message :
    dell-wmi: Unknown key 0 pressed

    Adding a debugging printk in dell-wmi.c after line 222 like this :

    printk(KERN_INFO "dell:wmi 0x%x , 0x%x \n", buffer_entry[1], buffer_entry[2]);

    dmesg now shows :

    dell:wmi 0x0 , 0xe009
    dell-wmi: Unknown key 0 pressed

    So for some reason buffer_entry[1] is used although it is empty.

    Falling back to buffer_entry[2] in case buffer_entry[1] is 0x0 makes
    the button work.

    I suspect it might be better to fix the "dell_new_hk_type" logic though

    I had submitted this as but repeating the
    information and patch
    here as per Andrew Morton's suggestion.
