Mathieu confirmed this morning that using hid_hw_raw_request instead
of hid_hw_request while _setting_ the input_mode works for this
particular touchscreen. So I think we will simply switch to use this
sync operation instead of relying on the async one. We will need to
test this change a little bit, but it should be safe for BT and I2C at
least.

So, yes, we will drop this patch and have a better one in the next few
days. Thanks for holding this one :)

Cheers,
Benjamin
