| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | c8sectpfe driver selects CONFIG_FW_LOADER_USER_HELPER_FALLBACK by some reason, but this option is known to be harmful, leading to minutes of stalls at boot time. The option was intended for only compatibility for an old exotic system that mandates the udev interaction, and not a thing a driver selects by itself. Let's remove it.

| * | [media] media/v4l2-ctrls: fix setting autocluster to manual with VIDIOC_S_CTRLAntonio Ospite2015-10-201-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 5d0360a4f027576e5419d4a7c711c9ca0f1be8ca it's not possible anymore to set auto clusters from auto to manual using VIDIOC_S_CTRL. For example, setting autogain to manual with gspca/ov534 driver and this sequence of commands does not work: v4l2-ctl --set-ctrl=gain_automatic=1 v4l2-ctl --list-ctrls | grep gain_automatic # The following does not work v4l2-ctl --set-ctrl=gain_automatic=0 v4l2-ctl --list-ctrls | grep gain_automatic Changing the value using VIDIOC_S_EXT_CTRLS (like qv4l2 does) works fine. The apparent cause by looking at the changes in 5d0360a and comparing with the code path for VIDIOC_S_EXT_CTRLS seems to be that the code in v4l2-ctrls.c::set_ctrl() is not calling user_to_new() anymore after calling update_from_auto_cluster(master). However the root cause of the problem is that calling update_from_auto_cluster(master) overrides also the _master_ control state calling cur_to_new() while it was supposed to only update the volatile controls. Calling user_to_new() after update_from_auto_cluster(master) was just masking the original bug by restoring the correct new value of the master control before making the changes permanent. Fix the original bug by making update_from_auto_cluster() not override the new master control value.

| * | [media] smiapp: Export OF module alias informationJavier Martinez Canillas2015-10-201-0/+1

So technically there's no need for a driver to export the OF table since currently it's not used. In fact, the I2C device ID table is mandatory for I2C drivers since a i2c_device_id is passed to the driver's probe function even if the I2C core used the OF table to match the driver. And since the I2C core uses different tables, OF-only drivers needs to have duplicated data that has to be kept in sync and also the dev node compatible manufacturer prefix is stripped when reporting the MODALIAS. To avoid the above, the I2C core behavior may be changed in the future to not require an I2C device table for OF-only drivers and report the OF module alias. So, it's better to also export the OF table to prevent breaking module autoloading if that happens.

The problem is that, by being maintained on a separate file and not being updated for years, it got outdated. So, for example, some callback parameters were changed, but the DocBook were still using the old stuff. As a first step to fix it, let's move the documentation of struct dmx_demux into demux.h and fix the parameters used there. For now, don't document any other field nor touch the descriptions that got moved, letting this job to other patches. That makes easier to review the patch. PS.: Please notice that an additional patch will be needed in order to fix the return values (some uses non-existent return codes) and to the functions and callbacks mentioned at the descriptions.
