If anyone has any objections, please let me know. ------------------ From: Hans de Goede [ Upstream commit ba9de350509504fb748837b71e23d7e84c83d93c ] Calling get_wireless_feature_index() from probe() causes the wireless_feature_index to only get set for unifying devices which are already connected at probe() time. It does not get set for devices which connect later. Fix this by moving get_wireless_feature_index() to hidpp_connect_event(), this does not make a difference for devices connected at probe() since probe() will queue the hidpp_connect_event() for those at probe time. This series has been tested on the following devices: Logitech Bluetooth Laser Travel Mouse (bluetooth, HID++ 1.0) Logitech M720 Triathlon (bluetooth, HID++ 4.5) Logitech M720 Triathlon (unifying, HID++ 4.5) Logitech K400 Pro (unifying, HID++ 4.1) Logitech K270 (eQUAD nano Lite, HID++ 2.0) Logitech M185 (eQUAD nano Lite, HID++ 4.5) Logitech LX501 keyboard (27 Mhz, HID++ builtin scroll-wheel, HID++ 1.0) Logitech M-RAZ105 mouse (27 Mhz, HID++ extra mouse buttons, HID++ 1.0) And by bentiss: Logitech Touchpad T650 (unifying) Logitech Touchpad T651 (bluetooth) Logitech MX Master 3B (BLE) Logitech G403 (plain USB / Gaming receiver) Fixes: 0da0a63b7cba ("HID: logitech-hidpp: Support WirelessDeviceStatus connect events") Signed-off-by: Hans de Goede Link: https://lore.kernel.org/r/20231010102029.111003-4-hdegoede@redhat.com Signed-off-by: Benjamin Tissoires Signed-off-by: Sasha Levin --- drivers/hid/hid-logitech-hidpp.c | 20 +++++++++----------- 1 file changed, 9 insertions(+), 11 deletions(-) diff --git a/drivers/hid/hid-logitech-hidpp.c b/drivers/hid/hid-logitech-hidpp.c index 2c212f835e8c5..fa1c7e07e220b 100644 --- a/drivers/hid/hid-logitech-hidpp.c +++ b/drivers/hid/hid-logitech-hidpp.c @@ -1757,15 +1757,14 @@ static int hidpp_battery_get_property(struct power_supply *psy, /* -------------------------------------------------------------------------- */ #define HIDPP_PAGE_WIRELESS_DEVICE_STATUS 0x1d4b -static int hidpp_set_wireless_feature_index(struct hidpp_device *hidpp) +static int hidpp_get_wireless_feature_index(struct hidpp_device *hidpp, u8 *feature_index) { u8 feature_type; int ret; ret = hidpp_root_get_feature(hidpp, HIDPP_PAGE_WIRELESS_DEVICE_STATUS, - &hidpp->wireless_feature_index, - &feature_type); + feature_index, &feature_type); return ret; } @@ -3999,6 +3998,13 @@ static void hidpp_connect_event(struct hidpp_device *hidpp) } } + if (hidpp->protocol_major >= 2) { + u8 feature_index; + + if (!hidpp_get_wireless_feature_index(hidpp, &feature_index)) + hidpp->wireless_feature_index = feature_index; + } + if (hidpp->name == hdev->name && hidpp->protocol_major >= 2) { name = hidpp_get_device_name(hidpp); if (name) { @@ -4241,14 +4247,6 @@ static int hidpp_probe(struct hid_device *hdev, const struct hid_device_id *id) hidpp_overwrite_name(hdev); } - if (connected && hidpp->protocol_major >= 2) { - ret = hidpp_set_wireless_feature_index(hidpp); - if (ret == -ENOENT) - hidpp->wireless_feature_index = 0; - else if (ret) - goto hid_hw_init_fail; - } - if (connected && (hidpp->quirks & HIDPP_QUIRK_CLASS_WTP)) { ret = wtp_get_config(hidpp); if (ret) -- 2.42.0
