Hi, This is a batch of patches touching drm for preparing for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add

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
