Subject: [PATCH 1/4] common.h: reintroduce region_overlap() as, old_region_overlap()
Date: Sat, 18 Sep 2021 00:39:01 +0200
Message-ID: <3b36e00c-84fb-800a-5128-cb38f2be0868@axentia.se> (raw)
In-Reply-To: <781e128b-14f3-3577-e433-f6a13fff8159@axentia.se>

The region_overlap() function was removed as unused by patch
81ca755487 ("common.h: remove unused region_overlap()")
but only because the last user was prematurely removed by patch
070de908da ("ARM: remove PBL_FORCE_PIGGYDATA_COPY")

A clean reverts is not appropriate, as the previous name of
the function has been repurposed by patch
04e2aa516e ("common.h: move and rename lregion_overlap()")
