Subject: [PATCH net-next v2 8/9] bnxt_en: Refactor bnxt_dl_info_get().
Date: Mon, 12 Oct 2020 05:10:53 -0400	[thread overview]
Message-ID: <1602493854-29283-9-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1602493854-29283-1-git-send-email-michael.chan@broadcom.com>

[-- Attachment #1: Type: text/plain, Size: 8019 bytes --]

From: Vasundhara Volam <vasundhara-v.volam@broadcom.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().
