Subject: [PATCH net-next v2 8/9] bnxt_en: Refactor bnxt_dl_info_get().
From: Vasundhara Volam <vasundhara-v.volam@...adcom.com>
Add a new function bnxt_dl_info_put() to simplify the code, as there
are more stored firmware version fields to be added in the next patch.
Also, rename fw_ver variable name to ncsi_ver for better naming while
copying to devlink info_get cb.
v2:
Ensure active_pkg_name string is NULL terminated when copied to
devlink.
Return directly from the last call to bnxt_dl_info_put().
