Could you please test the patch and check if the return results are
now consistent and that it won't break anything?
I have tested the patch and it worked without problems.

I could not noticed the bug because
the device was registered without any error messages,
and it seemed to work even with the bug.
(Though actually I was wrong and missed that
the device does not work after reboot or re-plugging).
After applying this patch, I have confirmed that the device
now works after reboot/re-plugging without any problems.
note:
The patched func: gl861_i2c_read_ex was used in device's early init,
called from d->props->power_ctrl (from dvb_usbv2_init).
But dvb_usbv2_init does not check the return value of it,
and if the device had been initialized previously
it can work even with the interrupted init process in power_ctrl().
I suspect all whole friio_reset() function is not needed as it has
worked even I/O has been broken.
Also tuner I2C adapter is implemented wrong (I think I mentioned that
earlier). As tuner sits behind demod I2C-adapter/gate that whole logic
should be on demod driver.
