[PATCH] checkpatch: remove obsolete CONFIG_EXPERIMENTAL checks

[PATCH] checkpatch: remove obsolete CONFIG_EXPERIMENTAL checks

[Ruslan Bilovol]

Config EXPERIMENTAL has been removed from kernel in 2013
(see 3d374d0: "final removal of CONFIG_EXPERIMENTAL"),
there is no any reason to do these checks now.

Not quite removed:

$ git grep CONFIG_EXPERIMENTAL -- "*configs*" | wc -l
217

No objection from me though.

I just mean that config option is removed from Kconfig file.
These checkpatch checks have nothing to do with
"CONFIG_EXPERIMENTAL=y" lines that still live in many
defconfigs.

BTW, I can write quite simple script that will remove it from
defconfig as well and send to related maintainers in a
separate patch series, or alternatively you can do similar
thing proposed by you in RFC https://lkml.org/lkml/2015/7/16/725
