Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and

multiple of 8. The scanline pitch has be large enough to support
this. Therefore compute the byte size of 8 pixels in the given color

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 sometimes incorrect.
This series fixes this for most drivers. D
The ioctls MODE_CREATE_DUMB and MODE_MAP_DUMB return results into a
memory buffer supplied by user space. On errors, it is possible that
intermediate values are being returned. The exact semantics depends
on the DRM driver's implementation of these ioctls. Although this is
most-likely not a securit
Add drm_modes_size_dumb(), a helper to calculate the dumb-buffer
scanline pitch and allocation size. Implementations of struct
drm_driver.dumb_create can call the new helper for their size
computations.
There is currently quite a bit of code duplication among DRM's
memory managers. Each calculates
