From: Daniel Scheller <d.scheller@xxxxxxx> 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@xxxxxxxxxxxxxx>.
