Subject: [PATCH AUTOSEL 5.4 066/205] drm/amdgpu/vi: silence an uninitialized variable warning
Date: Thu, 16 Jan 2020 11:40:41 -0500 [thread overview]
Message-ID: <20200116164300.6705-66-sashal@kernel.org> (raw)
In-Reply-To: <20200116164300.6705-1-sashal@kernel.org>
From: Dan Carpenter <dan.carpenter@oracle.com>
[ Upstream commit 4ff17a1df7d550257972a838220a8af4611c8f2c ]
Smatch complains that we need to initialized "*cap" otherwise it can
lead to an uninitialized variable bug in the caller. This seems like a
reasonable warning and it doesn't hurt to silence it at least.
drivers/gpu/drm/amd/amdgpu/vi.c:767 vi_asic_reset_method() error: uninitialized symbol 'baco_reset'.
Fixes: 425db2553e43 ("drm/amdgpu: expose BACO interfaces to upper level from PP")
