Re: [PATCH] staging: tidspbridge: Fix potential NULL pointerdereference

[Dan Carpenter]

1) This patch doesn't do anything.  "dcd_key" points to freed memory
but it's not a NULL pointer.
2) The original pointer doesn't dereference "dcd_key" it just takes
the address of one of the elements.  I don't know the context and
can't say for sure that it's a wrong thing to do.

The code does look very suspect.  Why is it checking permisions
after we already removed the element and freed it?

But it's not a dereferencing freed memory bug.

dan carpenter
