Subject: [PATCH AUTOSEL 4.14 046/123] mlxsw: spectrum: Avoid -Wformat-truncation warnings
Date: Wed, 27 Mar 2019 14:15:10 -0400 [thread overview]
Message-ID: <20190327181628.15899-46-sashal@kernel.org> (raw)

[ Upstream commit ab2c4e2581ad32c28627235ff0ae8c5a5ea6899f ]
Give precision identifiers to the two snprintf() formatting the priority
and TC strings to avoid producing these two warnings:
drivers/net/ethernet/mellanox/mlxsw/spectrum.c: In function
'mlxsw_sp_port_get_prio_strings':
drivers/net/ethernet/mellanox/mlxsw/spectrum.c:2132:37: warning: '%d'
directive output may be truncated writing between 1 and 3 bytes into a
region of size between 0 and 31 [-Wformat-truncation=]
snprintf(*p, ETH_GSTRING_LEN, "%s_%d",
^~
drivers/net/ethernet/mellanox/mlxsw/spectrum.c:2132:3: note: 'snprintf'
output between 3 and 36 bytes into a destination of size 32
