[media] gpio-ir-recv: a couple signedness bugs
There are couple places where we check unsigned values for negative. I
changed ->gpin_nr to signed because in gpio_ir_recv_probe() we do:
if (pdata->gpio_nr < 0)
return -EINVAL;
I also change gval to a signed int in gpio_ir_recv_irq() because that's
the type that gpio_get_value_cansleep() returns and we test for negative
returns.
