Subject: [PATCH 06/11] Revert "drm: Switch DRM_DISPLAY_HDCP_HELPER to depends on"
Date: Mon, 22 Apr 2024 12:30:34 +0200
Message-Id: <a40e70a0abd3d841c23c107d452a43fdd70ef37a.1713780345.git.geert+renesas@glider.be>

This reverts commit 3166e7e6d935caaef07605a5c90773fbf9ffeaf4, as helper
code should always be selected by the driver that needs it, for the
convenience of the final user configuring a kernel.

The user who configures a kernel should not need to know which helpers
are needed for the driver he is interested in.  Making a driver depend
on helper code means that the user needs to know which helpers to enable
first, which is very user-unfriendly.
