image upside down, thinkpad x220 table

Description of problem:
The image of the webcam is upside down
Version-Release number of selected component (if applicable):
1. buy thinkpad x220 tablet
2. install fedora
3. start cheese
Image is upside down
Image not upside down
It seems libv4 got some quirk that thinks the webcam is installed upside down and so rotates the image. But - at least in my model - that assumption is wrong and the image ends up upside down.
I think it worked before some upgrade.
lsusb -v is attached. My guess is that the webcam is "04f2:b217"
I'm going to send you a private mail with the email address of the current upside-down quirk list maintainer, the problem with the x220 is that there are some models which need us to flip the image in software, and some which don't (like yours). We've been unable to exactly figure out how to determine what sort of model we're dealing with.
Once you've my mail, please send a mail to the upstream maintainer explaining your problem, he will likely reply with a request for a bunch of info. You can speedup the process by doing:
lsusb -v > lsusb.log
sudo dmidecude > dmi.log
And sending the 2 log files along with your first mail. Please CC me on the mail.
After you habe generated the DMI and USB data (there's a typo, it should read dmidecode) could you try to upgrade your BIOS (and Firmware) with the latest version provided by Lenovo?
This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora
'version' of '17'.
Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version prior to Fedora 17's end of life.
Bug Reporter: Thank you for reporting this issue and we are sorry that
we may not be able to fix it before Fedora 17 is end of life. If you
would still like to see this bug fixed and are able to reproduce it
against a later version of Fedora, you are encouraged change the
'version' to a later Fedora version prior to Fedora 17's end of life.
Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.
Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.
If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version.
Thank you for reporting this bug and we are sorry it could not be fixed.
