media: Kconfig: cleanup VIDEO_DEV dependencies media Kconfig has two entries associated to V4L API: VIDEO_DEV and VIDEO_V4L2. On Kernel 2.6.x, there were two V4L APIs, each one with its own flag. VIDEO_DEV were meant to: 1) enable Video4Linux and make its Kconfig options to appear; 2) it makes the Kernel build the V4L core. while VIDEO_V4L2 where used to distinguish between drivers that implement the newer API and drivers that implemented the former one. With time, such meaning changed, specially after the removal of all V4L version 1 drivers. At the current implementation, VIDEO_DEV only does (1): it enables the media options related to V4L, that now has: menu "Video4Linux options" visible if VIDEO_DEV source "drivers/media/v4l2-core/Kconfig" endmenu but it doesn't affect anymore the V4L core drivers. The rationale is that the V4L2 core has a "soft" dependency at the I2C bus, and now requires to select a number of other Kconfig options: config VIDEO_V4L2 tristate depends on (I2C || I2C=n) && VIDEO_DEV select RATIONAL select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE default (I2C || I2C=n) && VIDEO_DEV In the past, merging them would be tricky, but it seems that it is now possible to merge those symbols, in order to simplify V4L dependencies. Let's keep VIDEO_DEV, as this one is used on some make *defconfig configurations.

media: dvb-core: Kconfig: default to use dynamic minors All modern Linux distributions nowadays use udev or some alternative (like systemd). So, it makes sense to change the default to use dynamic minors. Please notice that this default doesn't enable any code. It just changes the dvb-core behavior.

media: remove redundant 'default n' from Kconfig-s 'default n' is the default value for any bool or tristate Kconfig setting so there is no need to write it explicitly. Also since commit f467c5640c29 ("kconfig: only write '# CONFIG_FOO is not set' for visible symbols") the Kconfig behavior is the same regardless of 'default n' being present or not: ... One side effect of (and the main motivation for) this change is making the following two definitions behave exactly the same: config FOO bool config FOO bool default n With this change, neither of these will generate a '# CONFIG_FOO is not set' line (assuming FOO isn't selected/implied). That might make it clearer to people that a bare 'default n' is redundant. ...

media: dvb-core: allow users to enable DVB net ULE debug This debug option is there for a long time, but it is only enabled by editing the source code. Due to that, a breakage inside its code was only noticed years after a change at the ULE handling logic. Make it a Kconfig parameter, as it makes easier for advanced users to enable, and allow test if the compilation won't be broken in the future.

[media] dvb_demux: convert an internal ifdef into a Kconfig option There are some ifdefs inside the dvb_demux that are meant to enable advanced debug capabilities, at the cost of being very verbose. Keeping those as internal ifdefs is a very bad idea, as it doesn't make easy to check if the code there was broken by some patch. So, let's add an explicit Kconfig option for it.
