The driver core ignores the return value of struct bus_type::remove()
because there is only little that can be done. To simplify the quest to
make this function return void, let struct ishtp_cl_driver::remove() return
void, too. All users already unconditionally return 0, this commit makes
it obvious that returning an error value is a bad idea.

Older compilers like gcc-4.8 don't see that the variable is
initialized when it is used:

Make sure to initialize it before returning an error from ish_query_loader_prop().

This driver adds support for loading Intel Integrated Sensor Hub (ISH) firmware
from host file system to ISH SRAM and start execution.
At power-on, the ISH subsystem shall boot to an interim Shim loader-firmware,
which shall expose an ISHTP loader device.
The driver implements an ISHTP client that communicates with the Shim ISHTP
loader device over the intel-ish-hid stack, to download the main ISH firmware.
