[dpdk-stable] patch 'drivers: fix sprintf with snprintf' has been queued to LTS release 17.11.6

[Yongseok Koh]

Hi,

FYI, your patch has been queued to LTS release 17.11.6

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objection by 03/13/19. So please
shout if anyone has objection.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] drivers: fix sprintf with snprintf

[ backported from upstream commit a1e8241a919f7239d16e63fbc41549b2c951e1ae ]

sprintf function is not secure as it doesn't check the length of string.
More secure function snprintf is used

Fixes: 828d51d8fc ("bus/fslmc: refactor scan and probe functions")
Fixes: e5cbdfc537 ("crypto/dpaa2_sec: add basic operations")
Fixes: b23d4e898a ("crypto/dpaa2_sec: add per dev mempool to store FLE")
Fixes: 623326dded ("crypto/dpaa2_sec: introduce poll mode driver")
Fixes: 7e3e2954e0 ("crypto/dpaa_sec: move mempool allocation to config")
Fixes: c3e85bdcc6 ("crypto/dpaa_sec: add crypto driver for NXP DPAA platform")
