I have recently purchased a Lenovo Yoga 900 and most everything is working
with a slightly modified 4.4-rc5 (https://lkml.org/lkml/2015/11/30/441 applied
to enable the touchpad itself), I am seeing two issues:

1) On suspend/resume, the touchpad is non-functional. A `modprobe -r i2c-hid;
 modprobe i2c-hid` "fixes" it.

The kernel emits:

i2c_hid i2c-SYNA2B29:00: failed to reset device.
dpm_run_callback(): i2c_hid_resume+0x0/0xc0 [i2c_hid] returns -61
PM: Device i2c-SYNA2B29:00 failed to resume: error -61

During the resume. So perhaps this is a timing issue (given that once
resumed, the
module reload does work?).

2) During boot, the following is emitted:

i2c_hid i2c-ITE8396:00: error in i2c_hid_init_report size:19 / ret_size:18

I'm not sure if this indicates a hardware or driver bug? With
i2c-hid.debug=1, I see:

i2c_hid i2c-ITE8396:00: report (len=19): 12 00 5a ff ff ff ff ff ff ff
ff ff ff ff ff ff ff ff 06
i2c_hid i2c-ITE8396:00: error in i2c_hid_init_report size:19 / ret_size:18

Any suggestions?

Thanks,
Nish
