Subject: [PATCH v1] drm/tegra: Correct DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT
Date: Sun, 30 May 2021 22:55:06 +0300	[thread overview]
Message-ID: <20210530195506.19124-1-digetx@gmail.com> (raw)

The format modifier is 64bit, while DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT
uses BIT() macro that is 32bit on ARM32.

The (modifier &= ~DRM_FORMAT_MOD_NVIDIA_SECTOR_LAYOUT) doesn't work as
expected on ARM32 and tegra_fb_get_tiling() fails for the tiled formats
on 32bit Tegra because modifier mask isn't applied properly. Use the
BIT_ULL() macro to fix this trouble.

Fixes: 7b6f846785f4 ("drm/tegra: Support sector layout on Tegra194")
