Changelog:
1, Fix trackpoint (red stick on the keyboard) lost after resume, verified;
2, force enable nosleep mode of RMI;
I didn't reproduce touchpad lost after resume, this change tries to fix
it.
3, add more debug info;
Notes:
1, i2c-i801 module should be loaded. touchpad/trackpoint should work at smbus
mode (intertouch=1).
2, If touchpad lost is still reproduced, please do the following steps and
upload the log below:
1) please add "rmi_core.debug_flags=0x7" in kernel parameter;
2) when touchpad lost after resume,
$ cat /proc/interrupts |grep rmi > rmi_irq.log
move mouse curse with touchpad even it is not moving.
$ cat /proc/interrupts |grep rmi >> rmi_irq.log
Then upload "journalctl -b 0 -k" and rmi_irq.log file.
Thanks for testing.
