bnx2x: fix potential memory leak in bnx2x_alloc_mem_bp()
Overview
Description
In the Linux kernel, the following vulnerability has been resolved: bnx2x: fix potential memory leak in bnx2x_alloc_mem_bp() If the allocation of fp[i].tpa_info fails, the error path will not free the struct bnx2x_fastpath allocated earlier, as it is not linked to the bp structure yet. Fix that by linking it immediately after allocation.
