Subject: [PATCH 09/13] timer: Remove users of expire and data arguments to DEFINE_TIMER
Date: Wed,  4 Oct 2017 16:27:03 -0700
Message-ID: <1507159627-127660-10-git-send-email-keescook@chromium.org> (raw)
In-Reply-To: <1507159627-127660-1-git-send-email-keescook@chromium.org>

The expire and data arguments of DEFINE_TIMER are only used in two places
and are ignored by the code (malta-display.c only uses mod_timer(),
never add_timer(), so the preset expires value is ignored). Set both
sets of arguments to zero.
