[SRU] [B/C/D/Unstable] [PATCH 0/1] Silent "Unknown key" message when pressing keyboard backlight hotkey

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1817063

[Impact]
Kernel message shows this once keyboard backlight hotkey gets pressed:
[ 3285.474172] dell_wmi: Unknown key with type 0x0010 and code 0x003f pressed 
It's for notification purpose, doesn't have any function.

[Fix]
Use KE_IGNORE for this type of event, so the keymap won't parse it.

[Test]
Once the patch is applied, the annoyance goes away.

[Regression Potential]
Low. This patch silence the useless message, no functional change.
