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

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
https://bugzilla.kernel.org/show_bug.cgi?id=16075 but repeating the
information and patch
here as per Andrew Morton's suggestion.


Thanks.
