Subject: [ 90/91] i2c: davinci: Free requested IRQ in remove

3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Marcus Folkesson <marcus.folkesson@...il.com>

commit 9868a060ccf769c08ec378a9829137e272e9a92c upstream.

The freed IRQ is not necessary the one requested in probe.
Even if it was, with two or more i2c-controllers it will fails anyway.
