Subject: [GSoC][PATCH 02/13] submodule--helper: introduce for_each_submodule_list()
Date: Tue,  8 Aug 2017 02:48:49 +0530
Message-ID: <20170807211900.15001-3-pc44800@gmail.com> (raw)
In-Reply-To: <20170807211900.15001-1-pc44800@gmail.com>

Introduce function for_each_submodule_list() and
replace a loop in module_init() with a call to it.

The new function will also be used in other parts of the
system in later patches.
