Re: [PATCH 1/1] drm/mm: optimize rb_hole_addr rbtree search in high addr mode
by kbuild test robot
Hi Nirmoy,
Thank you for the patch! Perhaps something to improve:
[auto build test WARNING on drm-intel/for-linux-next]
[also build test WARNING on drm-exynos/exynos-drm-next tegra-drm/drm/tegra/for-next drm-tip/drm-tip linus/master v5.7-rc3 next-20200429]
[cannot apply to drm/drm-next]
[if your patch is applied to the wrong git tree, please drop us a note to help
improve the system. BTW, we also suggest to use '--base' option to specify the
base tree in git format-patch, please see https://stackoverflow.com/a/37406982]
