Subject: [dpdk-stable] [PATCH 2/5] net/bnxt: fix to free allocated memory
Date: Wed, 25 Jul 2018 18:15:45 -0700	[thread overview]
Message-ID: <20180726011548.97788-3-ajit.khaparde@broadcom.com> (raw)
In-Reply-To: <20180726011548.97788-1-ajit.khaparde@broadcom.com>

In some cases we may not be freeing up memory allocated for certain
NVM commands because the code might have bailed out before reaching
rte_free(). This patch moves some code around to ensure the allocated
memory is freed before exiting the function.

Fixes: 19e6af01bb36 ("net/bnxt: support get/set EEPROM")
Cc: stable@dpdk.org
