Dan:
I recently sent in a patch for a similar problem in the gspca driver
(commit e469d0b09a19 "media: gspca: Fix memory leak in probe"). It
seems there may be similar issues in that driver: one single function
call tries to undo an indeterminate number of initializations.
I don't know enough about these subsystems to evaluate this. Can you
take a look at it?
Thank,
