Hi Lorenzo,

I'm seeing this error sometimes when resuming:
st_lsm6dsx_i2c 1-006a: failed to read fifo status (err=-13)

I doesn't matter if it's the ism330 or another wake source.
I have not enabled fifo readings.

I have tried the "[PATCH 00/13] various st_lsm6dsx fixes and missing 
bits​" same results.

The regmap_read in st_lsm6dsx_handler_thread for the event seems to be 
reading something as the event is reported correctly.

Later events are reported correctly...

/Sean
