[PATCH] drm/tegra: Fix window[0] base address corruption

Window uses shared stride for UV planes and tegra_dc_window struct defines array of 2 strides per window. That's not taken in account during setting up of the window addresses and strides, resulting in out-of-bounds write of the 3-rd (non-existent) V plane stride that overwrites Y plane base

[PATCH 1/3] drm/etnaviv: check for errors when enabling clocks

clk_prepare_enable() may fail, so we should better check for its return value and propagate it in the case of failure. Signed-off-by: Fabio Estevam --- drivers/gpu/drm/etnaviv/etnaviv_gpu.c | 30 -- 1 file changed, 24 insertions(+), 6 deletions(-) diff --git

[PATCH 2/3] drm/etnaviv: remove unneeded 'fail' label

In the etnaviv_gpu_platform_probe() error path the 'fail' label is used to just return the error code. This can be simplified by returning the error code immediately, so get rid of the unneeded 'fail' label. Signed-off-by: Fabio Estevam --- drivers/gpu/drm/etnaviv/etnaviv_gpu.c | 12

It does not make sense to check if table is NULL and afterwards to dereference it without considering the result. The inconsistency was indicated by cppcheck. An actual NULL pointer dereference was not observed. Signed-off-by: Heinrich Schuchardt --- drivers/gpu/drm/radeon/si_dpm.c | 2 +- 1

[PATCH 1/1] drm: avoid exposing kernel stack in compat_drm_getstats

The C standard does not specify the size of the integer used to store an enum. Hence in structure drm_stats32_t alignment bytes may exist. To avoid exposing bytes from the kernel stack it is necessary to initialize variable s32 completely. Signed-off-by: Heinrich Schuchardt ---
