Subject: [PATCH 1/8] efi: use typed function pointers for runtime services table [ver #4]
Date: Wed, 07 Dec 2016 11:11:25 +0000 [thread overview]
Message-ID: <148110908500.11513.7332744237852389781.stgit@warthog.procyon.org.uk> (raw)
In-Reply-To: <148110907725.11513.15923870640212286383.stgit@warthog.procyon.org.uk>
From: Ard Biesheuvel <ard.biesheuvel@linaro.org>
Instead of using void pointers, and casting them to correctly typed
function pointers upon use, declare the runtime services pointers
as function pointers using their respective prototypes, for which
typedefs are already available.
