-/* ENABLE_PVR150_WORKAROUND activates a workaround for a hardware bug that is
-   present in Hauppauge PVR-150 (and possibly PVR-500) cards that have
-   certain NTSC tuners (tveeprom tuner model numbers 85, 99 and 112). The
-   audio autodetect fails on some channels for these models and the workaround
-   is to select the audio standard explicitly. Many thanks to Hauppauge for
-   providing this information. */

+/* Some general notes on the atomic requirements of VIDIOC_G/TRY/S_EXT_CTRLS:
+
+   It is not a fully atomic operation, just best-effort only. After all, if
+   multiple controls have to be set through multiple i2c writes (for example)
+   then some initial writes may succeed while others fail. Thus leaving the
+   system in an inconsistent state. The question is how much effort you are
+   willing to spend on trying to make something atomic that really isn't.
+
+   From the point of view of an application the main requirement is that
+   when you call VIDIOC_S_EXT_CTRLS and some values are invalid then an
+   error should be returned without actually affecting any controls.
+
+   If all the values are correct, then it is acceptable to just give up
+   in case of low-level errors.
+
+   It is important though that the application can tell when only a partial
+   configuration was done. The way we do that is through the error_idx field
+   of struct v4l2_ext_controls: if that is equal to the count field then no
+   controls were affected. Otherwise all controls before that index were
+   successful in performing their 'get' or 'set' operation, the control at
+   the given index failed, and you don't know what happened with the controls
+   after the failed one. Since if they were part of a control cluster they
+   could have been successfully processed (if a cluster member was encountered
+   at index < error_idx), they could have failed (if a cluster member was at
+   error_idx), or they may not have been processed yet (if the first cluster
+   member appeared after error_idx).
+
+   It is all fairly theoretical, though. In practice all you can do is to
+   bail out. If error_idx == count, then it is an application bug. If
+   error_idx < count then it is only an application bug if the error code was
+   EBUSY. That usually means that something started streaming just when you
+   tried to set the controls. In all other cases it is a driver/hardware
+   problem and all you can do is to retry or bail out.
+
+   Note that these rules do not apply to VIDIOC_TRY_EXT_CTRLS: since that
+   never modifies controls the error_idx is just set to whatever control
+   has an invalid value.

- * gaps and now maintains a delay buffer, which is used to present
- * consistent timing behaviour to user space applications. Without the
- * delay buffer an ugly hack would be required in lircd, which can
- * cause sluggish signal decoding in certain situations.

- * - from the USB layer throuh probe/disconnect/irq
- *
- *   Careful placement of lirc_register_driver/lirc_unregister_driver

- *   called after lirc_unregister_driver returns.
- *
- * - by the timer callback
- *
- *   The timer is only running when the device is connected and the
- *   LIRC device is open. Making sure the timer is deleted by
- *   set_use_dec will make conflicts impossible.
