Subject: [PATCH v2] net/ice/base: fix gcc 12 warning stringop-overflow
Date: Thu, 23 Jun 2022 17:01:05 +0800	[thread overview]
Message-ID: <20220623090105.645154-1-wenxuanx.wu@intel.com> (raw)
In-Reply-To: <20220616103304.132368-1-wenxuanx.wu@intel.com>

From: Wenxuan Wu <wenxuanx.wu@intel.com>

gcc 12 with -O2 flag would raise the following warning:
../drivers/net/ice/base/ice_switch.c:7220:61: error: writing 1 byte into a
region of size 0 [-Werror=stringop-overflow=]
 7220 |           buf[recps].content.lkup_indx[i + 1] = entry->fv_idx[i];
      |           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~

This patch changed the type of fv_idx in struct ice_recp_grp_entry to
align with its callers which are also u8 type.

Fixes: 04b8ec1ea807 ("net/ice/base: add protocol structures and defines")
