Date: Sat, 29 Oct 2022 15:03:12 +0300 From: Eray Orçunus <erayorcunus@...il.com> To: platform-driver-x86@...r.kernel.org Cc: linux-kernel@...r.kernel.org, linux-input@...r.kernel.org, ike.pan@...onical.com, jikos@...nel.org, benjamin.tissoires@...hat.com, dmitry.torokhov@...il.com, hdegoede@...hat.com, mgross@...ux.intel.com, pobrn@...tonmail.com, Eray Orçunus <erayorcunus@...il.com> Subject: [PATCH v2 7/7] platform/x86: ideapad-laptop: Don't expose touchpad attr on IdeaPads with SYNA2B33 My 520-15IKB (2017) with SYNA2B33 doesn't have working VPCCMD_W_TOUCHPAD command - it's the touchpad program switches the touchpad instead on Windows. Considering all IdeaPads with SYNA2B33 touchpad produced in 2017/2018, it's very likely that none of the IdeaPads with SYNA2B33 support touchpad switching via EC. So let's add SYNA2B33 to the touchpads not switchable via EC.
