Subject: event/dpaa: fix portal allocation
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=5b8526445d53aa172abf77076ffc952a5c6d2d17;p=dpdk.git

event/dpaa: fix portal allocation

Checking if portal has been allocated is now required at the
caller of rte_dpaa_portal_init() API. This patch adds check
in the dpaa eventdev driver.

Fixes: 5d944582d028 ("bus/dpaa: check portal presence in the caller function")
