Subject: [PATCH AUTOSEL 5.4 19/26] net/cxgb4: Check the return from t4_query_params properly
Date: Fri, 24 Apr 2020 08:23:16 -0400	[thread overview]
Message-ID: <20200424122323.10194-19-sashal@kernel.org> (raw)
In-Reply-To: <20200424122323.10194-1-sashal@kernel.org>

From: Jason Gunthorpe <jgg@mellanox.com>

[ Upstream commit c799fca8baf18d1bbbbad6c3b736eefbde8bdb90 ]

Positive return values are also failures that don't set val,
although this probably can't happen. Fixes gcc 10 warning:

drivers/net/ethernet/chelsio/cxgb4/t4_hw.c: In function ‘t4_phy_fw_ver’:
drivers/net/ethernet/chelsio/cxgb4/t4_hw.c:3747:14: warning: ‘val’ may be used uninitialized in this function [-Wmaybe-uninitialized]
 3747 |  *phy_fw_ver = val;

Fixes: 01b6961410b7 ("cxgb4: Add PHY firmware support for T420-BT cards")
