Subject: app/bbdev: check memory allocation
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=bc4c9418ee0fc22c480c236846af7fbad923ba89;p=dpdk.git

app/bbdev: check memory allocation

Return value of a function 'rte_malloc' is dereferenced without
checking, and may result in segmentation fault.

This patch fixed it.

Fixes: 31a7853d1ed9 ("baseband/turbo_sw: support large size code block")
