3d88ba86 - Revert "HID: multitouch: Add support for lenovo Y9000P Touchpad"

Thu, 12 Dec 2024 08:53:10 +0000

Revert "HID: multitouch: Add support for lenovo Y9000P Touchpad"This reverts commit 251efae73bd46b097deec4f9986d926813aed744.Quoting Wang Yuli: "The 27C6:01E0 touchpad doesn't require the workaround and applying it would actually break functionality. The initial report came from a BBS forum, but we suspect the information provided by the forum user may be incorrect which could happen sometimes. [1] Further investigation showed that the Lenovo Y9000P 2024 doesn't even use a Goodix touchpad. [2] For the broader issue of 27c6:01e0 being unusable on some devices, it just need to address it with a libinput quirk. In conclusion, we should revert this commit, which is the best solution."Reported-by: Ulrich Müller Reported-by: WangYuli Link: https://lore.kernel.org/all/uikt4wwpw@gentoo.org/Signed-off-by: Jiri Kosina List of files: /linux-6.15/drivers/hid/hid-multitouch.c

e8a05819 - HID: multitouch: make mt_set_mode() less cryptic

Mon, 28 Oct 2024 19:07:50 +0000

HID: multitouch: make mt_set_mode() less crypticmt_set_mode() accepts 2 boolean switches indicating whether the device(if it follows Windows Precision Touchpad specification) should reporthardware buttons and/or surface contacts. For a casual reader it iscompletely not clear, as they look at the call site, which exact modeis being requested.Define report_mode enum and change mt_set_mode() to accept is asan argument instead. This allows to write: mt_set_modes(hdev, HID_LATENCY_NORMAL, TOUCHPAD_REPORT_ALL);or mt_set_modes(hdev, HID_LATENCY_HIGH, TOUCHPAD_REPORT_BUTTONS);which makes intent much more clear.Reviewed-by: Benjamin Tissoires Signed-off-by: Dmitry Torokhov Link: https://patch.msgid.link/Zx_hBvg5Qa3KU3ta@google.comSigned-off-by: Benjamin Tissoires List of files: /linux-6.15/drivers/hid/hid-multitouch.c
