Subject: [PATCH AUTOSEL 5.0 06/99] HID: input: add mapping for Expose/Overview key

From: Dmitry Torokhov <>

[ Upstream commit 96dd86871e1fffbc39e4fa61c9c75ec54ee9af0f ]

According to HUTRR77 usage 0x29f from the consumer page is reserved for
the Desktop application to present all running user’s application windows.
Linux defines KEY_SCALE to request Compiz Scale (Expose) mode, so let's
add the mapping.
