[PATCH RESEND 03/14] [media] ddbridge: bump ddbridge code to version 0.9.29

Daniel Scheller
2017-07-23T18:16:41Z

This huge patch bumps the ddbridge driver to version 0.9.29. Compared to
the vendor driver package, DD OctoNET including GTL link support, and all
DVB-C Modulator card support has been removed since this requires large
changes to the underlying DVB core API, which should eventually be done
separately, and, after that, the functionality/device support can be added
back rather easy.

While the diff is rather large, the bump is mostly a big refactor of all
data structures. Yet, the MSI support (message signaled interrupts) is
greatly improved, also all currently available CI single/duo bridge cards
are fully supported.

More changes compared to the upstream driver:
- the DDB_USE_WORKER flag/define was removed, kernel worker functionality
will be used.
- coding style is properly fixed (zero complaints from checkpatch)
- all (not much though) CamelCase has been fixed to kernel_case

Great care has been taken to keep all previous changes and fixes (e.g.
kernel logging via dev_*(), pointer annotations and such) intact.

Permission to reuse and mainline the driver code was formally granted by
Ralph Metzler <rjkm@metzlerbros.de>.
