Mass changes like this go nowhere, and if they do, will cause unnecessary conflicts that could have been trivially avoided.

There is currently a mixture of octal and symbolic permissions uses in files in drivers/gpu/drm and one file in drivers/gpu. There are ~270 existing octal uses and ~115 S_<FOO> uses. Convert all the S_<FOO> symbolic permissions to their octal equivalents as using octal and not symbolic permissions is preferred by many as more readable. see: https://lkml.org/lkml/2016/8/2/1945 Done with automated conversion via: $ ./scripts/checkpatch.pl -f --types=SYMBOLIC_PERMS --fix-inplace <files...> Miscellanea: o Wrapped modified multi-line calls to a single line where appropriate o Realign modified multi-line calls to open parenthesis o drivers/gpu/drm/msm/adreno/a5xx_debugfs.c has a world-writeable debug permission for "reset" - perhaps that should be modified Signed-off-by: Joe Perches <joe@perches.com> --- drivers/gpu/drm/amd/amdgpu/amdgpu_debugfs.c | 2 +- drivers/gpu/drm/amd/amdgpu/amdgpu_pm.c | 98 +++++++++++----------- drivers/gpu/drm/amd/amdgpu/amdgpu_ring.c | 3 +- drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c | 9 +- drivers/gpu/drm/armada/armada_debugfs.c | 4 +- drivers/gpu/drm/drm_debugfs.c | 6 +- drivers/gpu/drm/drm_debugfs_crc.c | 4 +- drivers/gpu/drm/drm_sysfs.c | 2 +- drivers/gpu/drm/i915/gvt/firmware.c | 2 +- drivers/gpu/drm/i915/i915_debugfs.c | 8 +- drivers/gpu/drm/i915/i915_perf.c | 2 +- drivers/gpu/drm/i915/i915_sysfs.c | 22 ++--- drivers/gpu/drm/i915/intel_pipe_crc.c | 2 +- drivers/gpu/drm/msm/adreno/a5xx_debugfs.c | 5 +- drivers/gpu/drm/msm/msm_perf.c | 4 +- drivers/gpu/drm/msm/msm_rd.c | 4 +- drivers/gpu/drm/nouveau/nouveau_debugfs.c | 2 +- drivers/gpu/drm/omapdrm/displays/panel-dsi-cm.c | 11 ++- .../drm/omapdrm/displays/panel-sony-acx565akm.c | 6 +- .../drm/omapdrm/displays/panel-tpo-td043mtea1.c | 10 +-- drivers/gpu/drm/radeon/radeon_pm.c | 26 +++--- drivers/gpu/drm/radeon/radeon_ttm.c | 4 +- drivers/gpu/drm/sti/sti_drv.c | 2 +- drivers/gpu/drm/tinydrm/mipi-dbi.c | 4 +- drivers/gpu/drm/ttm/ttm_bo.c | 2 +- drivers/gpu/drm/ttm/ttm_memory.c | 12 +-- drivers/gpu/drm/ttm/ttm_page_alloc.c | 6 +- drivers/gpu/drm/ttm/ttm_page_alloc_dma.c | 6 +- drivers/gpu/drm/udl/udl_fb.c | 4 +- drivers/gpu/host1x/debug.c | 12 +-- 30 files changed, 138 insertions(+), 146 deletions(-)
