This is an updated series of fixes rebased on the interface-data memory leak
discovered by Lennart.
One of the reasons that I missed it was that the interface data was allocated
in probe rather than attach, which in itself is a bug as the memory would not
get released if usb-serial probe failes before attach returns successfully. The
third patch fixes this.
I also split out the fix for the port-data memory leak in the error path of
attach that was part of my previous patch. This way the first three patches can
be backported to most (all?) stable trees, whereas the last patch applies to
v3.6 (which contains the (in)famous 0998d063100 ("device-core: Ensure drvdata
= NULL when no driver is bound" commit).
I included Lennart's patch with an updated commit message for completeness.
Lennart, if you care to test this series before it is applied that would be
much appreciated.
Thanks,
Johan
