The lirc daemon now fails to detect a raw IR device, both for transmit and receive.

| | | | | | | | | | | | | | | | | | | This commit adds a new property DTV_SCRAMBLING_SEQUENCE_INDEX. This 18 bit field, when present, carries the index of the DVB-S2 physical layer scrambling sequence as defined in clause 5.5.4 of EN 302 307. There is no explicit signalling method to convey scrambling sequence index to the receiver. If S2 satellite delivery system descriptor is available it can be used to read the scrambling sequence index (EN 300 468 table 41). By default, gold scrambling sequence index 0 is used. The valid scrambling sequence index range is from 0 to 262142. Increase the DVB API version in order userspace to be aware of the changes.

* media: lirc: when transmitting scancodes, block until transmit is doneSean Young2017-12-181-2/+2
| | | | | | | | | | | | | | | | | The semantics for lirc IR transmit with raw IR is that the write call should block until the IR is transmitted. Some drivers have no idea when this actually is (e.g. mceusb), so there is a wait. This is useful for userspace, as it might want to send a IR button press, a gap of a predefined number of milliseconds, and then send a repeat message. It turns out that for transmitting scancodes this feature is even more useful, as user space has no idea how long the IR is. So, maintain the existing semantics for IR scancode transmit.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are several problems with regards to the return of FE_SET_PROPERTY. The original idea were to return per-property return codes via tvp->result field, and to return an updated set of values. However, that never worked. What's actually implemented is: - the FE_SET_PROPERTY implementation doesn't call .get_frontend callback in order to get the actual parameters after return; - the tvp->result field is only filled if there's no error. So, it is always filled with zero; - FE_SET_PROPERTY doesn't call memdup_user() nor any other copy_to_user() function. So, any changes to the properties will be lost; - FE_SET_PROPERTY is declared as a write-only ioctl (IOW). While we could fix the above, it could cause regressions. So, let's just assume what the code really does, updating the documentation accordingly and removing the logic that would update the discarded tvp->result.
