crash when unloading+loading snd_hda_intel

I used yast2 sound
to reconfigure my sound-card.
In there it was shown as unconfigured even though I was already using it.
after it finished, snd_hda_intel was not loaded
so I did modprobe snd_hda_intel
which caused a GPF in driver_probe_device
btw: I would prefer to not crash my machine again,
because re-syncing the 3TB RAID1 always takes a long time.
# cat /etc/modprobe.d/50-sound.conf
options snd slots=snd-hda-intel
# 5Dex.9zCmC9gVD38:SBx00 Azalia (Intel HDA)
alias snd-card-0 snd-hda-intel
The kernel looks old. Any reason not to use the released version?

I think that was only installed after a the crash
when I did zypper up
I you think, that 4.1.13 contains a fix
which was missing in 4.1.6-10, feel free to close the bug.

Yeah, I remember vaguely a similar issue, but don't remember when it got fixed :)
In anyway, this should have been fixed in the latest version, and I can't reproduce this. So, let's close it now. Feel free to reopen if you see it again.
I casually stumbled on a similar crash today, and this comes from a different culprit: namely, when user does reload too quickly, the driver crashes due to the race between the probe and the removal.
Just calling flush_work() before remove is enough. I'll paper over this now.

The fix patch is merged to relevant branches now. Let's close again.
