Hello, please keep codes in the array sorted.

Hi Pali,

I thought I sorted it... I'll fix it, thanks!

Before is value 0xe001 and your new values are 0x01xx. Most of values
are 0xeXXX, so it is quite unusual that Dell allocated values with
different pattern.

Also, could you please include into commit message for which Alienware
devices is change needed? It would help to detect devices which will be
fixed by your change.

And please add some comment into source file above those two new codes
for which are needed, in similar way how we have commented/documented
other key codes.

It is a bit unusual but it corresponds with the user report

	dell_wmi: Unknown key with type 0x0000 and code 0x0109 pressed
	dell_wmi: Unknown key with type 0x0000 and code 0x0150 pressed

and I also checked the acpidump.

Sure, the model is Alienware m18 r1 AMD.

I said "some" in the commit message because it's very likely other
Alienware models also use these codes.

Make sure that you include Dell.Client.Kernel@dell.com in case they have 
any comments.

I added them to CC.
