Fix mapping for non-zero starting coordinates
While the gralloc API allows for specifying the starting coordinates (L,T), it seems this doesn't really work. No other gralloc implementations found use the rectangle bounds. Not exactly sure how this ever worked, but it broke recently with AOSP master. Signed-off-by: Rob Herring <robh@kernel.org>
