From 3cfd956b02ac7a9fb5f2414171f834871931fbd0 Mon Sep 17 00:00:00 2001 From: Hao Wei Tee Date: Mon, 22 May 2017 18:38:55 +0800 Subject: platform/x86: ideapad-laptop: Squelch ACPI event 1 Don't simply throw this to userspace via the sparse_keymap (which does not have a mapping for scancode 1), as this causes KEY_UNKNOWN to be emitted, which is a nuisance and of no use at all (it is not the right way to expose this ACPI event to userspace, anyway, and the original intention of the commit which added this (cfee5d63767b2e7997c1f36420d008abbe61565c) was only to suppress an unhandled event log message).
