4.2.8-ckt2 -stable review patch. If anyone has any objections, please let me know.
---8<------------------------------------------------------------
From: Hui Wang <hui.wang@xxxxxxxxxxxxx>
commit c7b60a89516beb20a352ec85c73a8fccd5becf26 upstream.
Then users can remap the keycode from userspace. If without the remap,
the input device will pass KEY_MICMUTE to userspace, but in X11 layer,
it uses KEY_F20 rather than KEY_MICMUTE for XF86AudioMicMute. After
adding the keycode map, users can remap the keycode to any value users
want.
