[dpdk-dev] [PATCH 1/3] crypto/octeontx: fix non null terminated string

[Anoob Joseph <anoob.joseph@caviumnetworks.com>]

If the length of string pointed by 'name' is equal to or greater than
the sizeof cptvf->dev_name string, the resultant string will not be
null terminated. Using strlcpy would make sure the string would always
be null terminated.

Fixes: 0dc1cffa4d33 ("crypto/octeontx: add hardware init routine")
