Emu10k1 driver stop working since kernel 4.13 update.
Same issue with the last 4.13 rc5 version.
It' Fedora rawhide kernel.

I've no problem with kernel 4.12  and later.

I suspect this is caused by https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=d42fe63d58392f29e82e17c02f10e8cd3f45f17f,

This should be reported to the upstream maintainers.

you pushed this right away as 0b36f2bd28d, so i think this is fixed since v4.13-rc6.
