[PATCH v2 3/8] drm/fb-helper: Add simple init/fini functions

[Matt Gattis]

ah, yeah have to agree it was pretty tough figuring that out at first, I
was pretty green with kernel space. But considering i just wrote a working
linux DRM kernel driver with minimal knowledge of kernels or even really
how embedded devices share memory resources... good job is all I have to
say.

anyway, what's one small layer of code abstraction when we're doing it all
in the name of abstracting our code to non-existance at run-time? These DRM
modules are all just directing each other where to find the resources, and
since everyone knows what an image is made up of, it's a fairly small
overhead to encapsulate across each barrier.  I'd say split it up even
more... for example there could be one module that directs the interface
between SPI transport layers and graphic buffers/ux, and one that directs
instructions/buffers/ux back and forth from userspace to the proper
transport layer and proper rendering layer (which we seem to be missing...
i'm sure it could be reused in any case where two devices on a separate bus
need to communicate either directly to each other or to the rendering
layers).  I could have been pretty happy not even having to know what DMA
was to code what was missing, which was just the spi transmission
instructions.
