musl building problem expected `i32`, found `u64`

commit 8a2d6bf80725a8252545e2f7d8cc12b279846726

I suppose this is a musl problem:

help: you can convert a `u64` to an `i32` and panic if the converted value doesn't fit

It compiles with just (as suggested):

 463 |                     if libc::ioctl(drm_device.as_raw_fd(), ioctl_num.try_into().unwrap(), &mut create_blob) != 0 {

@realroot2185 could you let me know if this works with the latest commit? Looks like an error in the libc crate. There shouldn't be a different type for musl and glibc targets.

It works now, thanks.
