[PATCH v2 00/25] drm/dumb-buffers: Fix and improve buffer-size calculation
Dumb-buffer pitch and size is specified by width, height, bits-per-pixel
plus various hardware-specific alignments. The calculation of these
values is inconsistent and duplicated among drivers. The results for
formats with bpp < 8 are incorrect.
This series fixes this for most drivers. Default scanline pitch and
buffer size are now calculated with the existing 4CC helpers. There is
a new
