Unnessecary use of Option<u8>

[QuantumEF]

The following functions return an option:

seify-bladerf/src/types/dev_info.rs

Lines 33 to 36 in 4e3568d

	pub fn usb_bus(&self) -> Option<u8> {
	// TODO: Why is this an option?
	Some(self.0.usb_bus)
	}

seify-bladerf/src/types/dev_info.rs

Lines 41 to 44 in 4e3568d

	pub fn usb_addr(&self) -> Option<u8> {
	// TODO: Why is this an option?
	Some(self.0.usb_addr)
	}

Is there a specific reason for this, or was it just an oversight/assumption when doing initial work for the BladeRF bindings?

Yeah we can drop this.

I was under the impression that on macos, bus id is not exposed. I'm pretty sure this is not the case but even if it was, id rather expose directly how libbladerf presents things
