Subject: [PATCH 0/2] drm/vkms: Use alpha value for blending

The first patch of this series reworks part of the blend function to
improve the readability and also for preparing it for using alpha value.
The second patch updates the blend function for applying alpha value for
a fully transparent blend. After applying this patchset,
pipe-a-cursor-alpha-transparent in kms_cursor_crc start to pass.

This patchset depends on:
