== SRU Justification ==
A bug has been introduced on mainline by commit
"9ef449c6b31bb6a8e6dedc24de475a3b8c79be20" and this bug affects both
Oneiric and Precise. There's no upstream fix yet (couldn't even find
similar bug reports), but this will affect all users using the ENE IR
transceiver.
== Fix ==
The bug was introduced by accidentally moving the pnp_port_start()
invocation to a later stage in the device driver probe function,
while the goal was just to move the ISR and the pnp_port_start()
invocation. This patch fixes this.
== Impact ==
Users with an ENE IR transceiver will not be able to use it without
this fix.
== Test Case ==
Simply try to use the device, for example using a remote control.

i have a hp infrared RC6 remote,
it was working out-of-the-box with kernel linux-image-3.2.0-24-generic,
but doesnt work anymore with 3.2.0-25 or 3.2.0-26
Ubuntu 12.04 x64
linux-image-3.2.0-24-generic = 3.2.0-24.38 - works
linux-image-3.2.0-25-generic = 3.2.0-25.40 - doesnt work

Would it be possible for you to test a few upstream kernels? I'd first like to have you test the latest mainline kernels, to see if this bug is already fixed:
v3.5-rc3: http://
Also, since this appears to be a regression, can you test the following two kernels to see if they are the proper ones to bisect between:
v3.2.16: http://
and
v3.2.17: http://
I expect 3.2.16 to not have the bug. It would be good to know if 3.2.17 is when the bug was introduced.
