[PATCH 11/11] Revert "drm/display: Make all helpers visible and switch to depends on"

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This reverts commit d674858ff979550a0e97b4ac766f2640f0d9d7e7, 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.
