[PATCH 4.7 041/141] i40iw: Fix double free of allocated_buffer

From: Greg Kroah-Hartman
Date: Thu Oct 06 2016 - 04:36:48 EST

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


From: Mustafa Ismail <mustafa.ismail@xxxxxxxxx>

commit d41d0910d97f05be987d2d60de7e8685c108963b upstream.

Memory allocated for iwqp; iwqp->allocated_buffer is freed twice in
the create_qp error path. Correct this by having it freed only once in

Fixes: d37498417947 ("i40iw: add files for iwarp interface")
