Good day, I observe a possible regression on my HP ZBook Firefly 14 inch G9 Mobile Workstation PC/896D when I upgrade from linux-6.16-rc4 to linux-6.16-rc5: the notebook's touchpad doesn't work any more. On 6.16-rc4 I see this: [ 2.225387] input: SYNA30D9:00 06CB:CEA4 Mouse as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-SYNA30D9:00/0018:06CB:CEA4.0001/input/input7 [ 2.225451] input: SYNA30D9:00 06CB:CEA4 Touchpad as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-SYNA30D9:00/0018:06CB:CEA4.0001/input/input8 [ 2.225495] hid-generic 0018:06CB:CEA4.0001: input,hidraw0: I2C HID v1.00 Mouse [SYNA30D9:00 06CB:CEA4] on i2c-SYNA30D9:00 [ 2.360194] input: SYNA30D9:00 06CB:CEA4 Mouse as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-SYNA30D9:00/0018:06CB:CEA4.0001/input/input10 [ 2.360539] input: SYNA30D9:00 06CB:CEA4 Touchpad as /devices/pci0000:00/0000:00:15.0/i2c_designware.0/i2c-0/i2c-SYNA30D9:00/0018:06CB:CEA4.0001/input/input11 [ 2.361078] hid-multitouch 0018:06CB:CEA4.0001: input,hidraw0: I2C HID v1.00 Mouse [SYNA30D9:00 06CB:CEA4] on i2c-SYNA30D9:00 Whereas on 6.16-rc5 I get: [ 2.103592] i2c_hid_acpi i2c-SYNA30D9:00: HID over i2c has not been provided an Int IRQ [ 2.103610] i2c_hid_acpi i2c-SYNA30D9:00: probe with driver i2c_hid_acpi failed with error -22 All newer kernels (up to 6.17-rc3) show the same behaviour.
