Subject: [PATCH AUTOSEL 4.4 031/100] drm/radeon: remove set but not used variable 'size', 'relocs_chunk'
Date: Fri, 14 Feb 2020 11:23:15 -0500
Message-ID: <20200214162425.21071-31-sashal@kernel.org> (raw)
In-Reply-To: <20200214162425.21071-1-sashal@kernel.org>

From: zhengbin <zhengbin13@huawei.com>

[ Upstream commit e9f782dd22c0e17874b8b8e12aafcd3a06810dd0 ]

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/gpu/drm/radeon/r600_cs.c: In function r600_cs_track_validate_cb:
drivers/gpu/drm/radeon/r600_cs.c:353:22: warning: variable size set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/radeon/r600_cs.c: In function r600_cs_track_validate_db:
drivers/gpu/drm/radeon/r600_cs.c:520:27: warning: variable size set but not used [-Wunused-but-set-variable]
drivers/gpu/drm/radeon/r600_cs.c: In function r600_dma_cs_next_reloc:
drivers/gpu/drm/radeon/r600_cs.c:2345:26: warning: variable relocs_chunk set but not used [-Wunused-but-set-variable]

The first 'size' is not used since commit f30df2fad0c9 ("drm/radeon/r600:
fix tiling issues in CS checker.")

The second 'size' is introduced by commit 88f50c80748b ("drm/radeon/kms:
add htile support to the cs checker v3"), but never used, so remove it.

'relocs_chunk' is not used since commit 9305ede6afe2 ("radeon/kms:
fix dma relocation checking")
