Update smi_stream_dev.c #176

This fixes building on DragonOS_Pi64 - not sure if it breaks other OSes or not, though.

/home/ubuntu/cariboulite/driver/build/smi_stream_dev.c:1319:28: error: too many arguments to function ‘class_create’ 1319 | smi_stream_class = class_create(THIS_MODULE, DEVICE_NAME);

To confirm, this resolved the issue building CaribouLite on the latest DragonOS Pi64 (22.04 Ubuntu) after it switched to the 6.5 kernel for Pi5 support. I haven’t tested running the hat on a pi5 but it did run fine on the Pi4. I’ll add to DragonOS when I get a chance..

i had run through this on my pi4, then i swapped the hat and sd card to the pi5 and it all worked just the same.

hm but now im having an issue doing it from scratch on the pi 5, i can't get /dev/gpiomem to exist, there are only 0-4 variants, unlike my pi 4. will investigate/compare things later to see what's going on.

That’s strange so doing it from scratch on Pi4 is okay, transferring sd to pi5 is okay, but then you can’t do it from scratch? I swear in my case I did it from scratch on Pi5 but moved sd to the 4. I’ll do it all again asap.

@alphafox02 so it looks like the gpiomem interface was changed and this will require a change above my head here to get it working. i found someone saying that the 40-pin header was part of /dev/gpiomem4, but creating a symlink from gpiomem to gpiomem4 and running SoapySDRUtil caused the system to freeze up instantly. that's the only quick guess i had on this. pi 5 support may not be here yet, but at least you can build with the new kernel on a pi 4.

Did you check out the patch-1 branch?

unixpunk commented 5 months ago

all i know is it doesn't compile for me on ubuntu/dragonos unless i edit the file and remove "THIS_MODULE, ". Not sure if you're using latest 6.5 kernel yet or what you're working on there, but my experience is the opposite of yours...

I can confirm that I was able to build with this mod on a Pi 5 with Ubuntu/DragonOS but get the same GPIOMEM error. Would not compile without.
