[PATCH v3 0/7] drm/tegra: Miscellaneous enhancements

[Mark Zhang]

Hi Thierry,

Which version is this patch set based on? I tried to apply it on
linux-next 0206 & tot 0215 but failed:

Applying: drm: Add consistency check for page-flipping
Applying: drm/tegra: Add plane support
error: patch failed: drivers/gpu/drm/tegra/drm.h:121
error: drivers/gpu/drm/tegra/drm.h: patch does not apply
Patch failed at 0002 drm/tegra: Add plane support
When you have resolved this problem run "git am --resolved".
If you would prefer to skip this patch, instead run "git am --skip".
To restore the original branch and stop patching run "git am --abort".
