commit d0ac1a26ed5943127cb0156148735f5f52a07075 upstream.
As reported on:
https://lore.kernel.org/linux-media/20190627222020.45909-1-willemdebruijn.kernel@gmail.com/
if gp8psk_usb_in_op() returns an error, the status var is not
initialized. Yet, this var is used later on, in order to
identify:
- if the device was already started;
- if firmware has loaded;
- if the LNBf was powered on.
Using status = 0 seems to ensure that everything will be
properly powered up.
So, instead of the proposed solution, let's just set
status = 0.
