This will make sure applications which use the IN_FORMATS blob to figure out which modifiers they can use will pick up the linear modifier which is needed by mxsfb. Such applications will not work otherwise if an incompatible implicit modifier ends up being selected.
Since this got broken by the switch away for the simple display pipeline helper (ae1ed0093281939b80664a687689f12436c0e874) could you add a fixes tag? Cheers, -- Guido
