Subject: [PATCH 00/11] drm: Restore helper usability

	Hi all,

As discussed on IRC with Maxime and Arnd, this series reverts the
conversion of select to depends for various DRM helpers in series
"[PATCH v3 00/13] drm/display: Convert helpers Kconfig symbols to
depends on"[1], and various fixes for it.  This conversion introduced a
big usability issue when configuring a kernel and enabling DRM drivers
that use DRM helper code: as drivers now depend on helpers, the user
needs to know which helpers to enable, before the driver he is
interested even becomes visible.  The user should not need to know that,
and drivers should select the helpers they need.

Hence revert back to what we had before, where drivers selected the
helpers (and any of their dependencies, if they can be met) they need.
In general, when a symbol selects another symbol, it should just make
sure the dependencies of the target symbol are met, which may mean
adding dependencies to the source symbol.

Thanks for applying!

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
