Subject: [PATCH] platform/x86: hp-wmi: Handle Omen Key event
Message-ID: <Y8cjgu1ql+5+/NST@rishit-OMEN-Laptop-15-en0xxx>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
Precedence: bulk

Add support to map the "HP Omen Key" to KEY_PROG2. Laptops in the HP
Omen Series open the HP Omen Command Center application on windows. But,
on linux it fails with the following message from the hp-wmi driver:

[ 5143.415714] hp_wmi: Unknown event_id - 29 - 0x21a5
