[ Upstream commit 77ae0d8e401f083ca69c202502da4fc0e38cb1b7 ]
A Goodix touchpad doesn't work. Touching the touchpad can trigger IRQ but there's no input event from HID subsystem.
Turns out it reports some invalid data: [ 22.136630] i2c_hid i2c-DELL091F:00: input: 0b 00 01 00 00 00 00 00 00 00 00
After some trial and error, it's another device that doesn't work well with ON/SLEEP commands. Disable runtime PM to fix the issue.
