Subject: [PATCH 10/13] ui-shared: avoid initializing static variable to zero
Date: Sun, 8 Mar 2015 16:32:24 +0000 [thread overview]
Message-ID: <dac808f0d80f6316c646fed819f44bf77e24a4d6.1425832129.git.john@keeping.me.uk> (raw)
In-Reply-To: <cover.1425832128.git.john@keeping.me.uk>
Sparse complains that we are using a plain integer as a NULL pointer
here, but in fact we do not have to specify a value for this variable at
all since it has static storage duration and thus will be initialized to
NULL by the compiler.
