Subject: [PATCH 4.14 19/62] MIPS: bmips: mark exception vectors as char arrays
Date: Fri, 8 Nov 2019 19:50:07 +0100 [thread overview]
Message-ID: <20191108174735.046218064@linuxfoundation.org> (raw)
In-Reply-To: <20191108174719.228826381@linuxfoundation.org>
From: Jonas Gorski <jonas.gorski@gmail.com>
[ Upstream commit e4f5cb1a9b27c0f94ef4f5a0178a3fde2d3d0e9e ]
The vectors span more than one byte, so mark them as arrays.
Fixes the following build error when building when using GCC 8.3:
