Subject: HID: apple: option to swap the 'Option' ("Alt") and 'Command' ("Flag") keys.
From: Nanno Langstraat <langstr@xxxxxxxxx>
commit 43c831468b3d26dbe8f2e061ccaf1abaf9cc1b8b upstream.
Use case: people who use both Apple and PC keyboards regularly, and desire to
keep&use their PC muscle memory.
A particular use case: an Apple compact external keyboard connected to a PC
laptop. (This use case can't be covered well by X.org key remappings etc.)
