dm: core: Round up size when allocating so that it is cache line aligned
The size variable may not be always be a mulitple of ARCH_DMA_MINALIGN and using it to flush cache leads to cache misaligned warnings. Therefore, round up the size to a multiple of ARCH_DMA_MINLAIGN when allocating private data. Signed-off-by: Faiz Abbas <faiz_abbas@ti.com> Reviewed-by: Simon Glass <sjg@chromium.org>
