From: Daniel Scheller <d.schel...@gmx.net> This patch adds back the IOCTL API/functionality which is present in the upstream dddvb driver package. In comparison, the IOCTL handler has been factored to a separate object (and with that, some functionality from -core has been moved there aswell), the IOCTLs are defined in an include in the uAPI, and ioctl-number.txt is updated to document that there are IOCTLs present in this driver.
Signed-off-by: Daniel Scheller <d.schel...@gmx.net> --- This patch depends on the ddbridge-0.9.29 bump, see [1]. The functionality was part of the driver before.
