Subject: i40iw: Fix double free of allocated_buffer
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d41d0910d97f05be987d2d60de7e8685c108963b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

i40iw: Fix double free of allocated_buffer

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
i40iw_free_qp_resources().

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