Subject: [PATCH v2 iproute2-next 05/11] tc_util: fix clang warning in print_masked_type
Date: Tue, 11 Jan 2022 09:54:32 -0800 [thread overview]
Message-ID: <20220111175438.21901-6-sthemmin@microsoft.com> (raw)
In-Reply-To: <20220111175438.21901-1-sthemmin@microsoft.com>
Clang complains about passing a non-format string but the code here.
The old code was doing extra work the JSON case. JSON ignores one line mode.
This also fixes output format in oneline mode.
Fixes: 04b215015ba8 ("tc_util: introduce a function to print JSON/non-JSON masked numbers")
