Subject: [PATCH 13/28] cppcheck: Use inline suppression for ffsl()
Date: Wed, 28 Sep 2022 14:33:24 +1000 [thread overview]
Message-ID: <20220928043339.613538-14-david@gibson.dropbear.id.au> (raw)
In-Reply-To: <20220928043339.613538-1-david@gibson.dropbear.id.au>
[-- Attachment #1: Type: text/plain, Size: 1608 bytes --]
We define our own ffsl() as a weak symbol, in case our C library doesn't
include it. On glibc systems which *do* include it, this causes a cppcheck
warning because unsurprisingly our version doesn't pick the same argument
names. Convert the suppression for this into an inline suppression.
