Pairing wiimote leads to kernel null pointer derefence in hid_wiimote

Thank you for your report. The commit you refer to is applied already
to the Precise kernel since 3.2.0-25.40. Unfortunately, it looks like
the backport of this commit is incorrect and this is probably causing
the issue you're hitting.
I've reverted this commit, re-applied it and uploaded a
Yes, this kernel fixes the issue, thanks.

Probably unrelated to this bug: it crashes when unplugging the USB
bluetooth adapter (couldn't get a stack trace). I'll try to reproduce.

Title:
This could be an upstream issue, had similar problems when testing the above
mentioned 3.4 kernel.
Method of reproducing:
* plug USB bluetooth stick
* pair wiimote
* unplug USB bluetooth stick
* replug USB bluetooth stick
The actual problem (getting wiimote to work) is fixed though.

Thank you for testing. This new issue seems to be unrelated with the
initial problem. It looks like the driver fails to cleanly unregister
when the BT is unplugged and then it isn't able to reattach. This new
issue may also not be related with the wiimote driver itself, but with
the BT stack.

This might be the fix:

This doesn't make sense, the backtrace clearly states it visited
power_supply_powers(), but it seems there's no trace of that function in
the source?
apt-get source linux-image-`uname -r`
grep -R power_supply_powers linux-3.2.0/
yields nothing. Am I missing something?

Using the kernel from http://kernel.ubuntu.com/~kernel-
ppa/mainline/v3.4-precise/ this works fine, so I presume
217c8b2b1978aa4a02ce040a99c59ed3b6418fe5 fixes the issue.
