```rust
#[inline(never)]
pub fn my_syscall() -> bool {
	let mut ret = 0u8;
	let write_opt: Option<&u8> = Some(&ret);
	unsafe {
		core::arch::asm!("
			mov r12,{write}
			svc #123
		", write=in(reg) option_to_pointer(write_opt), clobber_abi("C"));
	}
	ret != 0
}
```

spot the issue with the syscall

For some reason, it returns zero even when the address passed into it has a one written to it
