[RFC PATCH v4 07/42] drm/vkms: Avoid reading beyond LUT array

2024-02-26 Thread Harry Wentland
When the floor LUT index (drm_fixp2int(lut_index) is the last index of the array the ceil LUT index will point to an entry beyond the array. Make sure we guard against it and use the value of the floor LUT index. v3: - Drop bits from commit description that didn't contribute anything of value
